Study of energy transfer between riboflavin (vitamin B_2) and AgNPs

摘要

Here, we report the studies on the interaction and formation of nanobiocomplex between silver nanoparticle (AgNPs) and vitamin B_2, i.e., riboflavin (RF). The binding study of AgNP to RF was studied by fluorescence, UV–Vis, and TEM techniques. AgNPs were prepared by reducing AgNO_3 with trisodium citrate. Prepared nanoparticles size obtained at 20 nm having surface Plasmon resonance band at 426 nm. The absorbance band of RF at 264, 374, and 444 nm changes significantly in the presence of AgNPs suggests that there is change in the chemical environment surrounding AgNPs. A fluorescence spectral change for a solution of RF upon the addition of AgNPs and rapid quenching is suggestive of a rapid adsorption of RF on AgNPs.
