Abstract: A non-enzymatic glucose biosensor was designed for the first time based on the employment of monodisperse Ni12P5 nanoparticles (NPs), which were fabricated by a modified one-pot hot-solution colloidal preparation method. The crystal structure, chemical composition and morphology of the Ni12P5 NPs was determined by using power X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectra, X-ray energy dispersive spectrometer. The developed sensor has presented excellent performance which involved a quick response time less than 3 s, a broad detection ranging from 0.002 to 4.2 mmol·L-1, a high sensitivity up to 1 572 mA·L·mol-1·cm-2, and a detection limit as low as 0.8 μmol·L-1. Additionally, it can be used to detect the glucose in the human blood serum with satisfactory result.
