Abstract: The present application relates to a biosensor for detecting an analyte comprising a first and second working electrode; a detection probe functionalized on the first working electrode, the detection probe comprising a reporter moiety and a recognition moiety for an analyte; a capture probe functionalized on the second working electrode; and a counter electrode. Each working electrode is configured to provide a change in signal if the analyte is present. The biosensor can be used to detect an analyte in a sample.

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.
