Abstract
MXene induced a stable SPR effect and high photoelectric conversion efficiency, which is beneficial for developing high-performance NIR self-powered biosensors. As a proof of concept, a sensitive NIR self-powered sensor was constructed by conjunction with an aptamer using Microcystin-RR as a model analyte, which is one of the most common and toxic hepatotoxins released by cyanobacteria.
