*3.7. Fluorescence-Based Assay*

Fluorescence-based binding was carried out on a Jasco spectrofluorometer FP 6200 (Jasco, Tokyo, Japan). HSA was excited at 280 nm with the emission range set at 300–400 nm. We analyzed the quenching data as per earlier published studies [32,50].

All the experiments were performed in triplicates.
