Detecting Pathogenic Microbes by a "Microbial Litmus Strip"

Liaohai Chen of Rush University Medical Center in the U.S. will develop nanoparticles which react to the presence of pathogenic microbes by releasing encapsulated substances that quickly amplify the binding signals. These nanoparticles can be placed on the tip of a litmus strip as a colorimetric assay to indicate the presence and concentration of pathogens.
