Harnessing microbes, one by one, to build a better nanoworld Taking a new approach to the painstaking assembly of nanometer-sized machines, a team of scientists at UW-Madison has successfully used single bacterial cells to make tiny bio-electronic circuits.The work is important because it has the potential to make building the atomic-scale machines of the nanotechnologist far easier. It also may be the basis for a new class of biological sensors capable of near-instantaneous detection of dangerous biological agents such as anthrax.
