Genes could build better chips

The chemical interaction between a metal and a protein from the organism might give life to elegant--and potentially commercial--films or crystals. A seashell, after all, is just chalk that has reacted with specialized proteins.

Californian start-up Cambrios is working on semiconductors and other computer components combining inorganic substances like cadmium sulfide with genetically engineered organisms.

U.K.-based Nanomagnetics is already studying how to make tiny memory cells out of proteins and Japanese Matsushita is conducting similar research. Other companies are looking at ways to harness photosynthesis for energy production.

One commercial use of Cambrios research could involve thin films. Today, putting different films together can require high temperatures and clean-rooms. Biological methods could cut costs by allowing manufacturers to conduct the process at lower temperatures.

Some of these substances could also be used in new types of pixels. Bioelectrical tools could be developed that could be sold to larger, established manufacturers.
