Abstract: This application relates to a photoactive product comprising: a catechol-containing compound, an amine-containing polymer, and photoactive material. The photoactive product can act as a photocatalyst and can be used in photoelectrodes for use in, for example, photoelectrochemical analyte sensing, including biosensing. The photoelectrodes modified with hybrid organic/inorganic materials can provide increased light absorption and charge separation, binding sites for attaching biorecognition probes, and built-in film-forming properties for well-adhered and uniform photoactive frameworks on the collector electrodes.
