In this work, a green strategy is performed to fabricate Pd3Ag nanopartides (NPs) using plant-extracted polysaccharide (Lilium brownie polysaccharide, LBP). As-obtained Pd3Ag nanocomposite (Pd3Ag-LBP/C) is surveyed including transmission election microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and powder X-ray diffraction (XRD). The result of glucose detection application shows that the Pd3Ag-LBP/C glassy carbon electrode (GCE) exhibits good stability and sensitivity. It can completely cover the normal blood glucose concentration (3-8 mM) with high sensitivity of 77.20 mu A mM(-1) cm(-2). This work undoubtedly has positive effects on green synthesis development. It not only proves the practicability of building nanomaterials by polysaccharide, but also offers an environmentally friendly way for fabricating other nanomaterials.
