Tiny fluorescent particles have been developed by University of Florida scientists which can be used for quick identification of bacteria by color coding them. It can certainly help in testing contaminants in food and prevention of bio terror attacks. The team at the university created nanoparticles with three colors - purple for Samonella typhimurium, blue for Escherichia coli and orange for Stapphylococcus aureus. As antibodies consist of proteins which stick to just one thing here nanoparticles containing antibodies cling onto a single type of bacteria.
When these nanoparticles are put along with three different types of bacteria they are color coded by these nanoparticles so that it could be easy to identify them with the aid of a confocal microscope. These findings have already been published in Bioconjugate Chemistry.
