Tracking Biofilms Using an Electrochemical Quartz Crystal Microbalance
20 May 2016

Biofilms are microbes attached to a surface. The microbes form a film on the surface, giving rise to the name biofilm. Some bacterial biofilms convert chemicals to electrical current on electrodes. Because of this function, they can be referred to as electrochemically active biofilms (EABs). Interest in EABs ranges from their function as bioanodes and biocathodes in microbial fuel cells to new types of biosensors as well as novel biosynthesis of sustainable chemicals. This application note shows results for Geobacter sulfurreducens, an oxygen-intolerant species of bacteria able to grow on electrodes.
