A versatile sensor capable of ratiometric fluorescence detection of trace water and turn-on detection of Cu²⁺ modulating the binding interaction of a Cu(<scp>ii</scp>) complex with BSA and DNA complemented by docking studies

Abstract

in various types of soils like clay soil, field soil and sand. The interaction of the PBA-Cu(II) complex with transport proteins like bovine serum albumin (BSA) and ct-DNA has been investigated through fluorescence titration experiments. Additionally, the structural optimization of PBA and the PBA-Cu(II) complex has been demonstrated by DFT, and the interaction of the PBA-Cu(II) complex with BSA and ct-DNA has been analyzed using theoretical docking studies.
