You want to see the nerve cell and the silicium chatting? I've got a picture today. It's a brain cell of a snail in Ringer solution. The sensors on the chip register the signals of the n.c. and forward them to a computer. Vice versa the tiny transistors are able to provoke the neuron by electrical impulses and the neuron answers with action potentials. Each of the more than 16.000 contacting sensors on one chip of the size of one square millimeter can register at least 2000 signals (5 millivolt = extremely low) per second. In this exchanging game the nerve cell is not damaged and, in these experiments stayed alive for several weeks. You might even put several nerve cells on one chip at the same time. And the silicium is not damaged by the salty solution.

At a Technical University in Nordrhein Westfalen (sorry, I do not know who and where) they discovered by chance a polymer which kills bacteria's and fungi (?). The effect is simple, electrostatic effects influence the natrium channels in that pathogenic agent which kills them.
It might be made even liquid that it can be used as a paint or cover for other materials.
