Physics Chemistry Engineering Life Sciences Mathematics Materials Science Computer Science Electronics Optics Imaging Multiple Technologies
Nano- materials medicine biotechnology lithography electronics magnetics robots Biodevices biomolecular machinery AI MEMS MicroElectroMechanical Systems NEMS NanoElectroMechanical Systems Biomimetic Materials Microencapsulation Many others Related and interwoven fields include, but are not limited to:
IS THIS SCIENCE FICTION? • 1959 - vision of Richard Feynman, Physicist • 1996 Nobel prize was awarded to Richard Smalley, Rice University • Billions being spent on research • MIT • University of Tokyo • Hottest research in military R&D, government sponsored health research
Nanotechnology We are at the point of connecting machines to individual cells Atoms <1 nm Cells thousands of nm DNA ~2.5 nm
Nanoscale is More Accurate • “Nano" • a Greek prefix meaning "one-billionth" • Basic unit of measure is a nanometer (nm) • a metric prefix that indicates a billionth part (10-9). • Nanoscale - characteristic dimensions are less than about 1,000 nanometers
“Just How Small is It?” • If a nanometer were scaled to the width of your little fingernail… • Your fingernail would be the size of Delaware • Your thumb would be the size of Florida
Nanoscale Science • Not a technology - it’s materials science • Features as small as one nanometer • one-billionth of a meter, or • a hundred-thousandth the width of a human hair • Hemoglobin = 6.5nm • Viruses are 10-100 nm • Human hair = 100,000nm
Nanoguitar – Cornell University • Ten microns (10 x 10-6 m) long, about the size of a red blood cell. • Thickness of a human hair is about 20 times the length of this guitar. • The "strings" (rods of silicon) are 50 nm wide or about 100 atoms across.
The Potential • Many scientists believe that soon—maybe 50 years from now—tiny robots … will be able to build or repair anything at the atomic and molecular level. • http://www.physicscentral.com/action/action-00-1-print.html
Potential of the Research • Improved electronic devices • cheaper flat-screen televisions • palm-size computers that recognize speech • Magnetic storage disks that could hold 100,000 times more data than current disks
The Vision • In the next 50 years, machines will get increasingly smaller--so small that thousands of these tiny machines would fit into the period at the end of this sentence.
The Vision • Within a few decades, we will use these nanomachines to manufacture consumer goods at the molecular level… • Make baseballs, telephones, cars, etc. in the same company
If we can manipulate single atoms… …the results could lead to a revolution in computing, electronics, energy, materials design, manufacturing, medicine, and numerous other fields.
Vision - Hype or Potential? • “Nanotechnology – the next big thing” • Investors beware! • Self-Assembly • Microscopic computer that assembles itself, atom by atom, then calculates at a speed faster than today's zippiest electronic chips
Self Assembly Uses Forces in Nature • Chemical attraction • Chemical bonds • Water-repellant • Biological attraction • Transfer of material through cell walls, DNA • Antibody-antigen reaction • Physical attraction • Magnetic fields • Electron charges
Self-Assembly at Millimeter Scales • Molecules want to form structures • Coded to do this • Order/complexity is “built in” to the components • Low energy requirements • Simple when it works, but don’t yet know the rules for how things aggregate • 5mm plastic self-assembled light-emitting diode (fits on a penny) • Whitesides, 2000
Molecular Nanotechnology • Molecular machines able to build objects to complex atomic specifications • Possibilities include: • molecular manufacturing systems able to construct computers smaller than living cells, • devices able to repair cells, • diamond-based structural materials, and • other molecular manufacturing systems.
Smallest object ever created by humans was sculpted by two laser beams focused across resin. The resin solidified only where the lasers crossed. Created by a team of researchers at Osaka University in Japan, the bull measures 10 microns from horns to tail, and seven microns across (1 micron = 1000 nm).
Nano Bull • Could sit on a single human blood cell • Can fabricate any structure of design. • Another team at Osaka University is developing devices to be implanted into the human body • Hope to combine the two techniques • Cell surgery or blood cell reparation
The Promise • Promises to be a new Industrial Revolution. • Global market for nanotech products to reach $700 billion by 2008 • Cheap products • 100% recyclable • The leanest manufacturing ever!!
VISIONS OF LIFE • Nanotechnology makes better social and economic conditions possible: • Every product made to customer specifications • Food plentiful • Diseases cured (Nanobiotechnology) • Clean up toxic waste • Create clean energy and bountiful clean water
C60 • “buckyballs” or fullerenes • Can encapsulate things • Many interesting properties • Superconductivity
Carbon Nanotubes • Tubes 10,000 X thinner than a human hair • An electronic device based on a single rolled-up sheet of carbon atoms • Discovered in 1991 by researchers at NEC • Potential for use as minuscule wires or in ultra-small electronic devices.
Nanotubes • Mechanically strong - held by covalent bonds • Folds and buckles but does not snap • Hollow interiors - put things inside them • Different radius • Tube is stable and won’t react on the outside • Conductive and respond to electrical fields
Carbon Nanotube Transistor • May 2002: Researchers built the world's first array of transistors out of carbon nanotubes -- tiny cylinders of carbon atoms that measure as small as 10 atoms across and are 500 times smaller than today's silicon-based transistors. • The breakthrough is a new batch process for forming large numbers of nanotube transistors.
The Threat • Displacing mature technologies • Disruptive in the workplace and the economy • Unintended consequences • Social impacts
“Today’s science fiction is often tomorrow’s science fact.” -Stephen Hawking
NANOTECH TRENDS • Convergence of computers, networks, biotech will create products never before imagined • Nanodevices will be invisible, intelligent and powerful • Used in every industry defining the limits of what is possible
NANOTECH TRENDS • Smaller than the head of a pin, surgical nanobots will operate from within the human body • Nano-biology will prolong life, prevent illness, and increase people’s health
NANOTECH SIGNS • StuffDust (nano-product created by San Francisco-based company minus9) • Marks objects and materials with serial numbers invisible to the naked eye - easily read with an optical microscope • Composed of micron-scale particles • Smaller than human hair • Carries a serial number • Marketed as efficient and secure way to mark computers, currency, explosives, toxic waste, etc. • New way to thwart thieves and improve inventory controls and manufacturing
NANOTECH SIGNS • World’s first implantable micro-machine, insulin-dispensing device was developed in 1998 • Miniature cochlea ear implants are giving back hearing to thousands of people • Cornell scientist created a nano-sized guitar to demonstrate the scale at which we can manipulate molecules today
VISIONS OF LIFE • Organic nano-engineering: • Computer biochips with organic materials to replace silicon • Viruses and proteins as molecular machines or nanofactories to build commercial products • New drug development
VISIONS OF LIFE • Synthetic DNA (nanogeonomics) to use for creating cloned life forms, robotics, human organs, and hybrid synthetic/organic compounds • Nano-informatics - use of advanced computers to “grow” nano-engineered products from informational models
Nanotechnology – What is it? • Rearrange matter with atomic precision • Central thesis of nanotechnology is that almost any chemically stable structure that is not specifically disallowed by the laws of physics can in fact be built.
Researchers have been building tiny motors inspired by machinery inside living cells. • These biomolecular motors run on adenosine triphosphate, or ATP, the same energy-rich molecule that powers chemical reactions within cells.
The Promise – Nanotechnology should let us: • Get every atom in the right place. • Make almost any structure consistent with the laws of physics that we can specify in molecular detail. • Have manufacturing costs not greatly exceeding the cost of the required raw materials and energy.
Health Issues • Some nanoparticles are so small, they can slip past the immune system or directly into the brain, bypassing the selective blood-brain barrier. • Makes nanoparticles useful for delivering much-needed drugs • But they might also deliver toxins.
Environmental Studies • Studying how nano-structured membranes could screen pesticides and harmful bacteria from water supplies. • Other scientists are developing low-cost, nano-scale iron hydroxide granules to remove arsenic from drinking water. • Still others have suggested that nano-sized sensors could help detect pollutants or monitor and correct changes in the ozone layer.
“If it can be done, it will be done” • “The same kinds of sweeping patents that have allowed biotech firms to "own life," in effect, may allow nanotech firms to "own" the building blocks of the entire physical world” • Hope Shand, director of research in the ETC Group, Carrboro, N.C.
