What's a personal

nanofactory?

To build a personal nanofactory (PN), you

need to start with a working fabricator, ananoscale device that can combine individual

molecules into useful shapes. A fabricatorcould build a very small nanofactory,

mec anoc em s rywork?

Mechanochemistry is hat the tool tip moleculecan be positioned by direct computer control,

so you can do this one reaction at a wide

variety of sites on the surface. Just a fewreactions give you a lot of flexibility in whatyou make.

Is nanotechnology bad or good?

Nanotechnology offers great potential for benefitto humankind, and also brings severe dangers.

While it is appropriate to examine carefully the

risks and possible toxicity of nanoparticles.products of nanoscale technology, the greatesthazards are posed by malicious or unwise useof molecular manufacturing. CRN's focus is ondesigning and promoting mechanisms for safedevelopment and effective administration of MM.
