Advances of Noble Bimetallic Nanoparticles in Detection of Glucose Level

Dr. David Medina Cruz et. al. investigate advances in noble bimetallic nanoparticles (BMNP) to more precisely measure and monitor glucose levels in the blood. They focus on the use of enzyme-free silver and gold nanoparticles, such as Ag-Au, Ag-Pt, Ag-Pd, and Au-Pt, and how their structures contribute to biosensor detection.
