Programmed bacteria build working electronic sensor

US engineers alter behaviour of programmed cells so that they build a 3D hybrid organic-metallic pressure sensor The possibility of growing electronic devices from bacteria seeded with metal nanoparticles has been raised by researchers from Duke University in North Carolina. The team has demonstrated that bacteria can be programmed to self-organise into a form that the cells themselves can transform into components of a working sensor. Black dots mark gold nanoparticles that have been attracted to the surface of pressure-sensitive domes constructed by engineered bacteria.
