A self-powered photodetector based on a ZnO nanoarrays/CdS/GaN structure with a responsivity as high as 176 mA W−1 at 300 nm.
A new immunoassay was designed for the detection of disease-related biomarkers (alpha-fetoprotein, AFP, as a model), coupling an aluminium (Al)/Prussian blue-based electrochromic display with a digital multimeter readout.
