A biosensor layered like lasagna

A new biosensor technology has been developed that uses static electricity to layer proteins on carbon nanotubes, allowing for precise detection of biological chemicals and environmental agents. The technique enables enzymes to self-assemble in a layer-by-layer manner on the nanotube, resulting in improved sensitivity and specificity.
