Summary: The study found that the binding of BHA to serum albumin occurs through static quenching, forming a relatively stable complex with hydrophobic interactions as the main binding mechanism. BHA has the capability to bind to specific sites on BSA, and the presence of other food additives weakens the binding of BHA to BSA.

Summary: The study investigated the binding behavior of a synthesized pyrimidine ligand with bovine serum albumin using spectrofluorometric, UV-Vis. spectrophotometric and docking examinations. The results showed that the quenching of BSA fluorescence by the pyrimidine ligand was due to a static mechanism, with the complex formation being unstable at high temperatures. Van der Waals forces and hydrogen bonding were proposed to be involved in the BSA-ligand interaction.

Summary: In this study, the effect of different aqueous extracting agents on the fluorescence properties of waste tea residue-based carbon dots (WTR-CDs) was investigated. The role of various aqueous media during the synthesis of WTR-CDs from carbonized carbon powder was examined, and the consequences of different extracting agents on the photophysical properties of the final WTR-CDs were discussed in detail. Interesting blue shift fluorescence spectra were observed in acidic medium and polar protic solvents, and the effect of cationic, anionic, and non-anionic surfactants on the fluorescence of WTR-CDs was evaluated. These findings have important implications for the future synthesis of carbon dots from various biomass-based precursors under different aqueous conditions.
