      The Business Of Nanotech

      There's still plenty of hype, but nanotechnology is finally moving from the
      lab to the marketplace. Get ready for cars, chips, and golf balls made with
      new materials engineered down to the level of individual atoms

      Pity the poor alchemists. They spent the Middle Ages in candle-lit
      laboratories, laboring to brew universal elixirs and to turn base metals
      into gold or silver. They failed utterly. By the dawn of the Scientific
      Revolution, researchers equipped with microscopes founded modern
      chemistry -- and dismissed alchemy as hocus-pocus.

      But it turns out alchemists were just a few centuries ahead of schedule.
      Today, in sparkling labs equipped with powerful microscopes, scientists on
      three continents are promising dramatic new materials and medicines that
      would make alchemists proud. This work takes place in the realm of
      nanotechnology, industry's tiniest stage. The standard unit of measurement,
      a nanometer, is a billionth of a meter -- barely the size of 10 hydrogen
      atoms in a row. In this universe entire dramas can unfold on the tip of a
      pin, and a sneeze packs the punch of a raging hurricane.

      Why so small? Researchers have discovered that matter at this tiny scale
      often behaves very differently. While some of the science behind this
      phenomenon is still shrouded in mystery, the commercial potential of the
      infinitesimal is coming sharply into focus. Familiar materials -- from gold
      to carbon soot -- display startling and useful new properties. Some transmit
      light or electricity. Others become harder than diamonds or turn into potent
      chemical catalysts. What's more, researchers find that a tiny dose of
      nanoparticles can transform the chemistry and nature of far bigger things,
      creating everything from fortified fenders to superefficient fuel cells.
      Engineers working at the nano scale have a brand-new tool kit that's full of
      wonder and brimming with potential riches.

      Now it's time to start cashing in. Throughout 2005, companies large and
      small will be rushing more nano-based products from labs to the marketplace.
      Consumers will encounter nanotechnology in the form of nick-proof trims on
      Hummers, Wilson tennis racquets with extra pop, even golf balls designed to
      fly straight. Investors, meanwhile, will be faced with a slew of bold
      announcements. On Feb. 1, for example, computer giant Hewlett-Packard Co.
      (HPQ ) disclosed a breakthrough in nanotechnology that, within a decade,
      could carry computing beyond today's silicon and transistors. "We are
      reinventing the computer at the molecular scale," says Stan Williams, an HP
      senior fellow and co-author of the report.

      For now, nano is starting out modestly. The biggest markets for
      nanoparticles remain in familiar products, from the black rubber filler in
      tires, a $4 billion industry, to the silver used in traditional photography.
      Lux Research Inc., a New York nanotech market researcher, estimates that
      only $13 billion worth of manufactured goods will incorporate
      nanotechnologies this year. That's little more than a rounding error in the
      global economy.

      Feverish Activity
      Yet new nano-based products that could have a far bigger impact are only a
      step or two away. Within the next two years, diagnostic machines with
      components built at the nano scale should allow doctors and nurses to carry
      pint-size laboratories in their briefcases, perhaps to test for HIV or count
      white blood cells on the spot. Nano sensors will scour airports and post
      offices for anthrax and sarin. Toward the end of the decade, scientists say,
      new computer memories composed of nanoparticles could conceivably pack the
      digital contents of the Library of Congress into a machine the size of a
      yo-yo. By that point, Lux predicts, nanotechnologies will have worked their
      way into a universe of products worth $292 billion (see table, "Nothing
      "Nano" about It").

      How does nanotechnology conjure up such surprises? Nature provides examples
      of this molecular magic. Think of coal compressing, over millennia, into
      diamonds. The gems are made of the same carbon atoms. But they've been
      rejiggered over time into orderly crystal patterns linked by superstrong
      chemical bonds. Soft becomes hard, sooty blackness becomes glittering

      These days scientists can pull off such transformations between coffee
      breaks. With atomic probes they manipulate molecules, one-upping Mother
      Nature. Delving into the nano realm gives them startling surprises right in
      the old periodic table of elements -- and they're filing a flurry of patents
      to lay claim to these miraculous materials. "It's a land grab," says Douglas
      Sharrott, a patent lawyer at Fitzpatrick, Cella, Harper & Scinto in New

      The questions around nano are no longer whether it's coming or if it's real
      but just how big it will be. Some see nano simply as a new material
      revolution, akin to the dawn of plastics. Others herald a transition as
      dramatic as mankind's advance from stone to metal tools. But those hazy
      predictions aside, the questions that are echoing from laboratories in Tokyo
      to the hectic offices of short-sellers on Wall Street are about money. Which
      nanotechnologies will create new fortunes, industries, and corporate champs?

      Activity on the ground is feverish. Some 1,200 nano startups have emerged
      around the world, half of them in the U.S. Companies that long labored in
      dull-as-dishwater materials businesses are finding that they can create a
      stir by trumpeting their mastery over age-old particles, from specks of
      ceramic to soot. Brokerages such as Merrill Lynch & Co. (MER ) and Punk,
      Ziegle & Co. are scouring the markets for nano-focused companies and
      plunking them into nano indexes. Meanwhile, investors, torn between an
      alluring new market and the fear of a dot-com-like bubble, are struggling to
      get a grip on exactly what nano means for them.

      Their confusion is understandable. Nano is not a single industry but a scale
      of engineering involving matter between 1 and 100 nanometers. Instead of one
      new phenomenon, like the Internet, nano offers new possibilities for
      thousands of materials that already exist. This means much of the early
      activity will likely take place at industrial giants. Already, 19 of the 30
      companies in the Dow Jones industrial index have launched nano initiatives.
      Says Margaret Blohm, manager of General Electric's (GE ) nanotechnology
      research and development program: "I lose sleep at night because
      expectations are so high."

      How do these tiny molecules create big new products? Sometimes size alone is
      the key. Consider DuPont's (DD ) new Voltron, a super-durable wire coating
      used in heavy-duty electric motors. If you looked at previous generations of
      such coatings through a powerful microscope, the chemical components would
      look loosely packed, with irregular spaces between the molecules. This
      structure leads the material to break down more easily. Voltron's nanoscale
      particles fill in many of the voids, making a stronger insulator that lasts
      longer. In DuPont's tests on electric motors, a coating of Voltron extended
      the time between failures by a factor of 10, to more than 1,000 hours. And
      since such motors consume an estimated 65% of U.S. electric power,
      lengthening their life and efficiency promises big energy savings. "This
      chemical combination can only be done with nanomaterials," says Krish
      Doraiswany, a senior planning manager for DuPont's nanotech research effort.

      Most of the early advances in nano will improve what we already have.
      Examples: lightweight army fatigues that resist chemical weapons and food
      packaging designed to keep last month's lettuce green and crunchy. Later
      this year, duffers will be able to buy golf balls manufactured by
      NanoDynamics Inc. in Buffalo, N.Y., that are designed to prevent a shift in
      weight as they spin. This should create balls that fly straight down the
      fairway and even hold a steadier line on the putting green. "If demand for
      the balls takes off, this could become a major business for us," says
      NanoDynamics CEO Keith Blakely, who plans to sell the balls for a pricey $5

      Beyond straight putts and fresh produce, can nano live up to its potential
      to create entirely new industries and corporate titans? The answer depends
      on how the players, from regulators to entrepreneurs, handle a host of
      thorny challenges. Governments must devise smart regulations to control new
      materials and therapies. Companies face logistical conundrums, such as
      carrying out quality control on shipments of minuscule carbon nanotubes and
      silicon crystals -- the I-beams and sheet glass of this industrial
      revolution -- that are virtually invisible.

      The nascent industry also must hammer out standards and enforcement
      practices that are sorely lacking. A 2004 study by Lux Research found that
      many of the 200 global suppliers of basic nanomaterials failed to deliver
      what they promised. "As a group they have a frighteningly poor track
      record," says Lux Vice-President Matthew Nordon. The upshot? Until the
      industry puts a qualified supply chain in place, only innovators working
      with world-class labs can count on reliable material. This limits access to
      nanotechnology and hurts its growth.

      An even greater challenge for nano industries is to ensure that their new
      materials are safe in the human body and in the environment. Setbacks could
      sink nano companies and even lead to a global backlash among the same
      activists who are raging against genetically modified food. "I'm worried
      about an overreaction to both the hype and the fear," says Kristen
      Kulinowski, an executive director at Rice University's Center for Biological
      & Environmental Nanotechnology.

      Such concerns rattle the equity markets. As recently as last summer, about a
      dozen nanotech companies were positioning themselves for initial public
      offerings. But last year's most widely anticipated IPO in the sector -- a
      $115 million offering for Nanosys Inc. in August -- was withdrawn at the
      last minute as investors cooled to a company rich in patents but still years
      from making a profit. Now the IPO market appears stalled, even for stars
      such as Nanofilm, a profitable Valley View (Ohio) manufacturer of optical
      films, and Konarka Technologies Inc., a Lowell (Mass.) leader in plastic
      solar panels.

      Premature Marketing?
      Doubts and confusion plague the market, where even the definition of nano is
      open to debate. When Merrill Lynch analysts released their Nano Index last
      April featuring 25 companies, critics howled that they were fueling hype --
      and that a few of the pharmaceutical outfits on the list were included
      simply because they engaged in the common practice of making molecules.
      Merrill retooled the list, limiting it to companies that publicly stress a
      commitment to nano. Still, Manuel P. Asensio, president of Asensio & Co., a
      short-seller that is still betting against the stock of one nano index
      company -- NVE Corp. (NVEC ), a maker of electronic sensor instruments --
      continues to grumble. "There is no market yet," he says. "Isn't Merrill
      attempting to create a retail fervor?" Merrill's Steven Milunovich, who
      directs its nanotech research, responds that the firm covers only three of
      the stocks on the index and compiles the list not to recommend investment
      vehicles but as a way to track the young industry. "It's a 30-year trend,
      and we're only at the beginning," he says.

      In today's cautious climate, investors are focusing less on dazzling visions
      and more on companies with real products, customers, and profits. The
      leading performer in Merrill's index in 2004 was MTS Systems Corp. (MTSC ),
      a 39-year-old testing-equipment company whose tools are widely used in nano
      labs. Its stock rose 80%. Harris & Harris Group Inc. (TINY ), a
      venture-capital firm with heavy investments in nano, saw its stock rise
      75% -- a sign that investors hold high hopes for the segment. But most
      businesses selling true nano products, from materials company Altair
      Nanotechnologies Inc. (ALTI ) to France's Flamel Technologies (FLML ), a
      medical supplier, suffered market declines through 2004. And the Merrill
      index fell another 12% in January, 2005.

      No doubt nano is in for its share of bumps, with flops sure to outnumber
      successes by a wide margin. Yet the technology of the tiny is on track to
      disrupt nearly everything in its path, including companies, industries, and
      universities. Why? At the atomic level the boundaries among biology,
      chemistry, physics, and electronics lose much of their meaning. The sciences
      start to merge. Many of the winners in nano will be those that can reach
      across old boundaries and create novel hybrids. Israeli biologists and
      electrical engineers, for example, have teamed up to attach dna to carbon
      nanotubes to create microscopic transistors. These assemble themselves in
      the lab following a biological blueprint. The result is an inanimate
      transistor -- but one that grows, like a tadpole or a toenail.

      Funding Magnet
      Companies that can bring such innovations to market stand to restructure
      entire industries. Korea's Samsung Group plans to produce TV displays
      featuring the most prominent building blocks of the Nano Age -- carbon
      nanotubes -- by 2006. If successful, these screens could be lighter,
      cheaper, brighter, and more energy-efficient than today's models. The
      technology would spread quickly from TVs to computer screens, even
      electronic billboards. GE is adding a new nano-focused wing to its R&D
      center in Niskayuna, N.Y. The company won't disclose the size of its
      investment but says a 50-member team of researchers is looking to seed nano
      into everything from medical technology to lighting to high-performance

      For entrepreneurs, nano spells funding. Venture capitalists have invested $1
      billion in nano companies, nearly half of it in the past two years.
      Meanwhile, government funding is holding steady at $4.7 billion annually,
      nearly equally divided among Asia, Europe, and North America. The cash is
      pouring into university labs and new nano corridors from Albany to Shanghai
      and Fukuoka prefecture in Japan. "Any professor with his head screwed on has
      moved research programs into nano," says Greg Blonder, a partner at
      Morgenthaler Ventures.

      Many of the early prospectors are focusing on health-care testing tools,
      which are far less regulated than medicines and therapies. LabNow Inc., an
      Austin (Tex.) startup, has its sights set on addressing the AIDS epidemic.
      Using minute channels and sensors, the company has devised a blood
      laboratory on a chip the size of a business card. The patient places a
      single drop of blood on the chip, which is then inserted into a small
      electronic reader. Within minutes, HIV/AIDS patients can get a count of
      their white blood cells -- a crucial metric for treatment. Currently that
      test takes weeks or months in poor regions of the world, where blood samples
      are trundled back and forth in slow trucks. Patients can die waiting for the
      results. LabNow's technology has the potential to speed AIDS treatment in
      much of the world -- and let LabNow cash in on the $5 billion global market
      for point-of-care testing. In October, LabNow got $14 million in equity
      funding from a consortium led by George Soros. The company hopes to roll out
      its systems in South Africa by the end of 2005.

      Red Flag
      More dramatic breakthroughs are expected within two or three years as
      companies developing novel medical procedures begin to emerge from the
      regulatory maze. Already, nano-ized versions of existing drugs are causing a
      stir. Last month, American Pharmaceutical Partners Inc. shares surged 50% on
      news that the Food and Drug Administration had approved the marketing of
      Abraxane, a nanoscale protein-based drug for the treatment of metastatic
      breast cancer. The nano version is able to squeeze into places in the body
      that its existing macro counterpart cannot without intolerable side effects.
      Further out, researchers are working on customized treatments, such as
      nanoparticles built to match the unique genetic profile of a patient's
      cancer cells -- and programmed to seek out and destroy them. Hundreds of
      these therapies are in the works. Most will fail. But if even a handful
      succeed, they could change medicine.

      To achieve such triumphs, nano companies must squelch fears about the
      effects of the particles in the body. Worries grew last spring when
      researchers at Southern Methodist University reported brain damage in a
      large-mouth bass that had been swimming in an aquarium stoked with common
      carbon-based nanoparticles known as buckyballs. Although far from
      conclusive, such findings raise red flags worldwide -- and they extend far
      beyond the networked legions of activists. Last year, giant reinsurer Swiss
      Reinsurance Co. warned against a rush into nano, citing "the unforeseeable
      nature of the risks it entails and the recurrent and cumulative losses it
      could lead to."

      One industry that should be able to tap nano's potential without those risks
      is semiconductors. As the circuits and pathways on the chips grow tinier,
      manufacturers are running into problems. Electrons tunnel through flimsy
      walls that are only several atoms thick. The electricity coursing through
      the intricate maze generates searing heat, which is increasingly costly and
      hard to control. As the industry struggles to maintain Moore's Law, which
      predicts the doubling of computing power every 18 months, costs are
      exploding. The price of a new semiconductor fabricating plant is projected
      to reach $10 billion by the end of the decade.

      Nano innovators aren't likely to replace the silicon chip anytime soon, but
      they could help ease the squeeze over the next decade. This process has
      already started with memory chips, the least complicated kind. Within two or
      three years, developers hope to make viable memory chips from
      spaghetti-shaped carbon nanotubes, each one only 1 nm wide. Further out,
      engineers are learning how to replace minuscule metal circuits and gateways
      on today's chips with new nano-engineered materials. IBM researchers have
      built transistors with carbon nanotubes that promise "a huge leap in
      performance while cutting heat loss," says Phaedon Avouris, a researcher at
      Big Blue's Nanometer Scale Science & Technology Labs.

      Despite this progress, it's a long hike to nanocomputing, not a sprint. HP
      researchers don't expect their platinum circuits to debut until 2011 at the
      earliest. And it won't be until much later in the next decade, say
      scientists, that nanotechnology may be able to provide a new architecture
      for faster computing in the post-Silicon era.

      The future of nanotechnology? It may seem strange now, but within a decade
      or so the term is likely to vanish from syllabuses and portfolios and remain
      part of company names only as a vestige of the past. After all, nano denotes
      only size. Once work on that scale becomes routine, that buzzword will fade.
      But the physical world -- medicines, metals, and even the roles the elements
      play -- will be utterly changed by this revolution, all brought about by
      bits far too small for the eye to see.
