Nanotechnology
Nanotechnology = 1-100 nm
Nanotechnology aims to manipulate atoms and molecules, making it possible to build machines on the scale of human cells, or create materials and structures from the bottom up with novel properties.
Nanotechnology could change the way almost everything is designed and made, from automobile tires, to vaccines, to objects not yet imagined.
Health issues Nanoparticles could be inhaled, swallowed, absorbed through
skin, or deliberately injected Could they trigger inflammation and weaken the immune
system? Could they interfere with regulatory mechanisms of enzymes and proteins?
Environmental issues Nanoparticles could accumulate in soil, water, plants;
traditional filters are too big to catch them
New risk assessment methods are needed National and international agencies are beginning to study
the risk; results will lead to new regulations

Summary: Science at the Nanoscale
An emerging, interdisciplinary science Integrates chemistry, physics, biology, materials
engineering, earth science, and computer science
The power to collect data and manipulate particles at such a tiny scale will lead to New areas of research and technology design Better understanding of matter and interactions New ways to tackle important problems in healthcare,
energy, the environment, and technology A few practical applications now, but most are years or
