Surface modification of TiO2 for photoelectrochemical DNA biosensors
Abstract
Abstract A photoelectrochemical (PEC) DNA biosensor is developed using surface‐modified TiO 2 nanoparticles (NPs) as a sensitive transducer. Different catecholates and gallates are used as sensitizers for TiO 2 NPs. The molecules are adsorbed on TiO 2 via the catecholate type bonding mechanism to enhance light absorption in the visible range. The adsorbed molecules act as charge transfer mediators and enhance photocurrent. Despite the similar …
