Basics Of Nanotechnology • Nanotechnology deals with tiny structures the size 100 nanometers or smaller. • A nanometer is one billionth of a meter. • For a start nanotech will help the fields of medicine, electronics, hybrid materials, and energy productions in the future. • The concept of nanotech first came about around 1959 • Nanotechnology is assembled by moving around molecules.
Understanding Molecules Molecules A molecule is a group of two or more atoms that stick together. Molecules (MOLL-uh-cyools) are so small that nobody can see them, except with an electron microscope. Everything on Earth and other planets is made of molecules, and so is some of the dust in space. Water Molecules
Nanotechnology Careers • Nanotechnology job projections are estimated to be nearly two million workers worldwide by 2015. • Some careers in nanotechnology are; • Electronics/semiconductor industry • Materials science including textiles, polymers, packaging, among other • Auto and aerospace industries • Sports equipment • Pharmaceuticals including drug delivery, cosmetics, among others • Biotechnology • Medical fields • Optoelectronics • Environmental monitoring and control • Food science including quality control and packaging • Forensics • University and federal lab research • National security • Military • And many more
Understanding Size • nm stands for nanometer (one billionth of a meter) • To be classified as nanotechnology the structure must be 100 nanometers or smaller • A flea is a 1000th of a meter while DNA is 100,000,000th of a meter. • A flea is 100,000 times bigger then DNA.
CURRENT NANOTECHNOLOGY • One of the current uses of nanotechnology is Carbon Nanotubes. • They are used to make: • clothes: waterproof tear-resistant textiles • combat jackets: MIT is working on combat jackets that use carbon nanotubes as ultra strong fibers and to monitor the condition of the wearer. • bridges: Carbon nanotubes may be able to replace steel in suspension bridges. • Super slick surfaces • Water filters • Just to name a few but here are hundreds of more applications for nanotubes.
Nanomedicine • Nanotechnology will give doctors the ability to deliver drugs right into cells, fight cancer, advanced surgery techniques, and even repair damaged cells. • Nanomedicine is being directly funded. • In 2005 the US National Institute of Health decided to fund a five year plan a five year plan to set up four Nanomedicine centers.
Nano Energy Production • Nanotechnology will greatly improves our efficiency in producing and storing energy. • It will improve batteries, solar cells, renewable energy, and improved energy savings. • Nanotechnology is already being used on batteries, The Lithium Ion battery is the most advanced battery created so far. • Solar cell efficiency will be greatly improved by 40% . • Energy savings will be improved by nanostructure insulation.
Nanoelectronics • Nanoelectronics is the way to make electronics smaller, smarter, and more powerful. • Nanoelectronics holds the promise of making computer processors more powerful then they are currently. • Nanoelectronics will also improve radios, energy production, and medical diagnostics.
NASA AND NANOTECH • NASA is interested in nanotechnology so they can create ultra small sensors, power sources, communication, navigation, and propulsion systems with very low mass.
Possibility of Nanotechnology Concept of Nanotechnology. Small computer chips will enable the ability to make smaller machines Concept of Nanotechnology. Tiny machines able to fix injured or sick blood cells.
Nanomaterials • Nanomaterials are applications with morphological (The form and structure of a material) features smaller than a one tenth of a micrometer in at least one dimension • Nanomaterials are being developed to be stronger and small enough to be used for tiny applications such as in the human body. • Examples of current nanomaterials are carbon nanotubes, nanoparticles, and fullerenes.
Micromachines • Examples of micromachines are medical nanobots, spy machines, and robotic insects. • Some current micromachines are a set of micro gears called are MEMS that are used in airbag sensors and in camera electronics. MEMS Medical Nanobot Concept
Buckyballs/Fullerenes • Fullerene are composed entirely of carbon, in the form of a hollow sphere, ellipsoid, tube, or plane. Spherical fullerenes are also called buckyballs. • Buckyballs are the smallest fullerene molecule in which no two pentagons share an edge. It is also the most common in terms of natural occurrence, as it can often be found in soot. • The fullerene was discovered in 1985 by Robert Curl, Harold Kroto and Richard Smalley at the University of Sussex and Rice University, who named it after Richard Buckminster Fuller, whose geodesic domes it resembles. • Uses for buckballs are; drug treatments, lubricants, electronic circuits, superconductors, and catalysts.
Nano Doom? • In 1986, engineer Eric Drexler warned that nanomachines could get out of control, and affect life on Earth. He suggested that they might wipe out all living matter, leaving a dusty waste called gray goo behind. Most scientists believe that this will not happen because nanomachines and MEM’s are not advanced enough. • There are also concerns that nanoparticles made in laboratories could escape in to the environment and harm plants and animals. • It does not look like any strong government regulations on nanotechnology will happen, unless an environmental crisis occurs.
