Role of Tris on the colorimetric recognition of anions with melamine-modified gold nanoparticle probe and the visual detection of sulfite and hypochlorite.
Colorimetric recognition and sensing of sulfite by melamine-modified gold nanoparticle is reported, using Tris-HCl as the operating buffer. Furthermore, indirect determination of hypochlorite is accomplished by its oxidation of sulfite.
