Latest Patents

Hongtao Yu holds a patent titled "Silver nanoparticle surface enabled self-assembly of organic dye molecules." This patent describes a novel method of fluorescence titration involving silver nanoparticles (AgNP) and various organic dyes, including methylene blue, rhodamine B, and rhodamine 6G (R6G). The research reveals that the interaction between the dye molecules and the AgNP leads to a unique self-assembly process, resulting in a micelle-like structure. The findings indicate that approximately 200,000 dye molecules can assemble on a single AgNP, forming about 36 layers of dye molecules. This self-assembly process is attributed to a "super-quenching" effect, which enhances fluorescence quenching due to the concentration of dye molecules on the nanoparticle surface.
