Fluorescence excitation of bacterial biofilms of S. epidermidis

Fluorescence excitation of bacterial biofilms of S. epidermidis, positioned under a fluorescence microscope. Copper electrodes were connected to a generator by means of two alligator clips. The biofilms were then subjected to pulsed electric fields in order to disorganise the bacteria. The extracellular matrix of the biofilms can be seen directly by microscopy. The purpose was to find a new non-invasive method to combat the pathogenic bacteria involved in nosocomial diseases.
