Development of photoelectrochemical methods for the detection of calprotectin based on nanocomposites prepared by one-step method

Gold nanoparticles(Au NPs)-sensitized tin dioxide (SnO<sub>2</sub>) semiconductor not only broadens the visible light absorption range of the material, but also easily forms a Schottky barrier at the heterogeneous interface, which effectively promotes the separation of photogenerated e-/...
