Nanowires That Behave Like Cells

Transistors with lipid membranes could make better interfaces for neural prosthetics.

Technology Review August 11, 2009

Researchers at the Lawrence Livermore National Laboratory have sealed silicon-nanowire transistors in a membrane similar to those that surround biological cells. These hybrid devices, which operate similarly to nerve cells, might be used to make better interfaces for prosthetic limbs and cochlear implants. They might also work well as biosensors for medical diagnostics.

Biological communication is sophisticated and remains unmatched in today's electronics, which rely on electrical fields and currents. Cells in the human body use many additional means of communication including hormones, neurotransmitters, and ions such as calcium. The nexus of biological communication is the cell membrane, a double layer of fatty molecules studded with proteins that act as gatekeepers and perform the first steps in biological signal processing.

The DARPA SyNAPSE project seeks to build systems that rapidly understand tons of data

The quest to mimic the best parts of human brain function on a highly intelligent computer to decypher tons of data quickly is heating up.

IBM this week got $16.1 million to kick up its part of a Defense Advanced Research Projects Agency research program aimed at rapidly and efficiently put brain-like senses into actual hardware and software so that computers can process and understand data more rapidly.
