- ... A simple and highly practical colorimetric method has been proposed for detection of chromium ions (Cr³⁺ and Cr⁶⁺) synchronously by sodium hyaluronate functionalized gold nanoparticles (SH-AuNPs). The SH-AuNPs were synthesized and characterized by UV–vis spectra and transmission electron microscopy (TEM). The colorimetric response of Cr³⁺ and Cr⁶⁺ can be performed simultaneously by the same probe ...
