Abstract
Nanozymes with high catalytic efficiency have been widely investigated and studied in various fields. Compared with natural enzymes, nanozymes with enzyme-mimicking properties possess the advantages of low-cost, scalability, high stability, and tunable catalytic performance. In this paper, platinum nanoparticles loaded on oxygenated nanodiamonds (Pt-ONDs) were synthesised through a one-step method as a highly efficient nanozyme to mimic the function of peroxidase. Based on this, a novel sensing strategy was developed by combining Pt-ONDs and gold bipyramids (AuBPs) for sensitive detection of glucose. The detection limit of this method was established at 0.2 μM (a few thousand times before the lowest detection limit of commercial glucometers), with a wide detection range from 0.2 to 400 μM, highlighting its potential for ultra-high sensitive glucose detection. This study may provide a novel strategy for the application of nanozymes and gold nanostructures for the sensitive detection of glucose. © 2024 The Author(s)
