Abstract:<p>Quantum
dots have proven to be strong candidates for biosensing applications in recent
years, due to their strong light emission properties and their ability to be
modified with a variety of functional groups for the detection of different
analytes. Here, we investigate the use
of conjugated carboxylated graphene quantum dots (CGQDs) for the detection of <i>E. coli</i>, using a biosensing procedure
that focuses on measuring changes in fluorescence quenching. Our CGQDs were conjugated wit… Show more
