Characterization of InP nanoparticles. a UV–Vis spectrum of InP nanoparticles suspension in ddH2O, and the control was spectrum of ddH2O. SEM image shows the morphology of InP after grinding and its size is distributed in 20–350 nm with less than 500 nm. Blue scale bar is 1 cm. b TEM image shows that InP nanoparticles were functionalized via (tannic acid)-based coating. Tannic acid and InP form supramolecular networks on the surface of the nanoparticles resulted in InP is negatively charged
