Title: Innovations in Fluorescence Quenching by Hua Deng
Introduction
Hua Deng is an accomplished inventor based in Baltimore, MD (US). He has made significant contributions to the field of fluorescence quenching through his innovative research. His work focuses on the interactions of organic dye molecules with silver nanoparticles, leading to groundbreaking findings in self-assembly processes.
Latest Patents
Hua Deng holds a patent titled "Silver nanoparticle surface enabled self-assembly of organic dye molecules." This patent describes a detailed study of fluorescence titration involving methylene blue, rhodamine B, and rhodamine 6G (R6G) using silver nanoparticles (AgNP). The research reveals that the interaction between the dye molecules and AgNP results in a unique fluorescence quenching behavior, characterized by an initial steep quenching curve followed by a flatter curve. At the turning point, approximately 200,000 dye molecules are found per single AgNP, indicating the formation of a micelle-like structure with around 36 layers of dye molecules.
