Summary: A simple and selective photoelectrochemical biosensor was developed for Hg2+ detection using zinc phthalocyanine dye-sensitized CdS and alginate as a carrier and binder. The biosensor exhibited a wide linear range and low detection limit, making it a promising platform for detecting other biomolecules. Detection of Hg2+ was achieved through specific binding with thymine-rich probe DNA, resulting in a decrease in photocurrent.

Summary: The introduction of a homojunction consisting of tungsten doped titanium dioxide nanorods and oxygen vacancies modified titanium dioxide nanosheets through a solid-state diffusion-hydrothermal method significantly enhances the photoelectrochemical water splitting performance. The combination of doping, oxygen vacancies, and homojunctions leads to a 136 times improvement in photocurrent density compared to pristine titanium dioxide nanorods. The downshift of the conduction band caused by tungsten doping reduces the recombination rate of electron-hole pairs, while the generation of oxygen vacancies facilitates carrier transfer and suppresses charge recombination. The type-II homojunction in the hierarchical nanostructure promotes the separation of photogenerated electron-hole pairs and increases the number of exposed active sites.
