Although core-shell structure is favored by many applications, preparing it with green way is rarely been reported. Herein, a core-shell structured Cu@Pd-CS nanocomposite is greenly fabricated utilizing a natural chitosan and applied to glucose detection. As-obtained Cu@Pd-CS nanoparticles were characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and powder X-ray diffraction (XRD). When applied to glucose detection, the Cu@Pd-CS exhibits good stability, sensitivity and anti-interference. Moreover, it has a good linear relationship in glucose concentrations range of 0.1 -1 mM with the sensitivity of 1.53 mu A mM(-1) cm(-2) and 1(-10) mM with the sensitivity of 23.00 mu A mM(-1) cm(-2). This work proves the practicability of building metal-based core-shell structure nanoparticles with green resources and glucose detection application.
