Application

Silver nanomaterials have unique physical, chemical and optical properties that are currently being leveraged for a wide variety of biological applications. Additionally, silver nanoparticles have an optical color that is a function of the silver nanoparticle′s size and shape. The strong coupling of silver nanoparticles to specific wavelengths of incident light can be utilized to develop ultrabright reporter molecules, highly efficient thermal absorbers, and nanoscale “antennas” that can amplify the strength of the local electromagnetic field.

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
