There is a need to develop innovative strategies to treat antibiotic resistance bacteria and cancer effectively. In this context, the present work focused on development of calcium oxide (CaO) and CaO modified with chitosan and dopamine nanocomposites (CaO–Cs–Dop) as potential antibacterial, anticancer, and antioxidant agents. The prepared nanoparticles were characterized using various characterization techniques. FTIR revealed the functional groups of prepared samples indicating the successful preparation of nanoparticles. XRD revealed the fcc cubic nature of CaO nanoparticles and the crystallite size was found to be 23 nm for CaO–Cs–DOP and 31 nm for CaO nanoparticles.

To address these challenges, a novel conductive hydrogel was synthesized through free radical polymerization, incorporating laponite (LA), tannic acid (TA), polyacrylic acid (PAA), and polyacrylamide (pAAm). An innovative approach was employed to enhance LA's dispersion through ionic liquid (IL) in water through electrostatic interactions.
