Green synthesis of Pd nanoparticles via extracted polysaccharide applied to glucose detection

A green innovation strategy is performed to synthesize palladium nanoparticles (Pd NPs) using Cynomorium songaricum polysaccharide (CSP). The structure and properties of the as-prepared Pd NPs are characterized by a set of techniques, including transmission election microscopy, X-ray photoelectron spectroscopy, powder X-ray diffraction and cyclic voltammetry. The results show that Pd NPs are well dispersed with a mean size of 4.2 nm. As-obtained Pd–CSP/C electrode exhibits good stability and anti-interference ability for glucose detection in electrochemical studies. It can completely cover the normal blood glucose concentration with high sensitivities of 17.7 µA mM −1  cm −2 , and excellent stability during long-term electrochemical detection. Compared with the commercial glucometer, the relative deviation of the measured samples was equal to 5.0%. Significantly, this study offers an environmental friendly polysaccharide way for fabricating nanomaterials, which would develop more nanomaterials for various application fields in future.
