We demonstrate that photoluminescent Si-dots exhibit intrinsic peroxidase-like activity, and can catalyze the oxidization of 3,3',5,5'-tetramethylbenzidine (TMB) by H2O2, and produce a color change. This strategy can be used to detect glucose with high sensitivity and selectivity.
我们证明了光致发光硅点具有内在的过氧化物酶样活性，能够催化过氧化氢对3,3',5,5'-四甲基联苯胺（TMB）的氧化反应，并产生颜色变化。该策略可用于高灵敏度和高选择性地检测葡萄糖。
