摘　　要：Metallic glass nanoparticles hold great promise as nonenzymatic glucose sensors due to their rich low-coordinated active sites and high biocompatibility.However,their non-periodic atomic structure and unclear structure-property relationship pose significant challenges for realizing and optimizing their sensing performance.In this work,Pd–Ni–P metallic glass nanoparticles with variable compositions were successfully prepared as nonenzymatic glucose sensors via a laser-evaporated inert-gas condensation method.The electrochemical tests show that the sensor based on Pd_(41·25)Ni_(41·25)P_(17.5)nanoparticles shows a wide linear detection range(0.003–1.31mM),high sensitivity(516μAmM^(−1)·cm^(−2)),and high stability(∼97.8%current retention after 1000 cycles).Local structural investigations using synchrotron pair distribution function and high-resolution microscopic techniques reveal a strong structural correlation within short-to medium-range orders in the Pd_(41·25)Ni_(41·25)P_(17.5)nanoparticles,which can be well retained after electrochemical cycling.These atomic-scale structural characteristics might be responsible for the high sensing performance.This study demonstrates the high applicability of Pd–Ni–P metallic glass nanoparticles as sensitive and stable non-enzymatic glucose sensors.
