General description

Our silver nanoparticles (10 nm in diameter) are spherical nanoparticles of metallic silver dispersed in an aqueous buffer. The particles have high electronic conductivity, high surface area, and, because of their tightly controlled particle size, fluoresce at 388 nm with a FWHM of only 50 nm.

Application

AgNPs dispersion can be used for a variety of applications such as optoelectronics, energy harvesting, and surface enhanced Raman spectroscopy (SERS).

Nanostructured Materials Through Ultrasonic Spray Pyrolysis

Advances in materials have often been led by the development of new synthetic methods that provide control over size, morphology and structure. The preparation of materials in a scalable and continuous manner is critical when development moves beyond lab-scale quantities.

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.
