This study, investigates the interplay of bovine serum albumin (BSA) with synthesized chitosan nanoparticles (CSNPs) utilizing regular-state fluorescence and UV-vis absorbance spectroscopy in addition to picosecond time-resolved fluorescence approach. The fluorescence quenching mechanism of BSA by CSNPs signifies the presence of each static and dynamic mechanism. The loading effectivity of BSA-CSNPs exhibited a lower by…
