‘Molecular computers’ act as tiny ID tags
September 5, 2006 | Source: NewScientist.com news service
Molecules capable of basic logic operations have been developed that could serve as tiny ID tags for identifying individual cells or nano-devices. The technique, called molecular computational identification (MCID), could produce tens of millions of unique tags.
The molecules use the presence of a chemical, or a mix of chemicals, as inputs, and give off light as output.
