Abstract

Reactive oxygen species selectively accelerated transitions between various silver nanodots. The blue was developed as an oxidant-resistant imaging agent and analyte reporter. In addition to the spectral response of nanodots to ROS, silver nanodots were formulated to detect analytes with excellent selectivity and picomolar detection limit when coupled to glucose oxidase.

摘要

活性氧物种选择性地加速了各种银纳米点之间的转变。蓝色纳米点被开发为一种抗氧化剂成像剂和分析物报告分子。除了纳米点对活性氧的光谱响应外，当与葡萄糖氧化酶结合时，银纳米点还被设计用于检测分析物，具有优异的选择性和皮摩尔检测限。
