In situ preparation of Tricholoma mushroom polysaccharide-g-poly(N,N-dimethyl acrylamide-co-acrylic acid)–CuO composite nanoparticles for highly sensitive and selective sensing of Th4+ in aqueous medium

A highly selective and sensitive sensor for Th⁴⁺ was developed for the first time using Tricholoma mushroom polysaccharide-based graft copolymer–CuO composite nanoparticles by colorimetric and electrochemical method.
