Development and characterization of hybrid films based on agar and alizarin red S for applications as non-enzymatic sensors for hydrogen peroxide

For the first time, the dye alizarin red S (ARS) was immobilized on indium tin oxide (ITO) electrodes via a layer-by-layer technique (LbL). This was achieved only when ARS was interspersed with the polymers agar (extracted from seaweed Gracilaria birdiae ) and PAH [poly(allylamine hydrochloride)]. A...
