Graphene oxide (GO) is a versatile material obtained by the strong oxidation of graphite. Among its peculiar properties, there is the outstanding ability to significantly alter the fluorescence of many common fluorophores and dyes. This property has been exploited in the design of novel switch-ON and switch-OFF fluorescence biosensing platforms for the detection of a plethora of biomolecules, especially pathological biomarkers and environmental contaminants. Currently, novel advanced strategies are being developed for therapeutic, diagnostic and theranostic approaches to widespread pathologies caused by viral or bacterial agents, as well as to cancer. This work illustrates an overview of the most recent applications of GO-based sensing systems relying on its fluorescence quenching effect.
氧化石墨烯(GO)是一种通过对石墨进行强氧化而获得的多功能材料。在其独特的性质中,有一项显著特性是能够显著改变许多常见荧光团和染料的荧光。这一特性已被应用于设计新型的开启和关闭荧光生物传感平台,用于检测大量生物分子,特别是病理生物标志物和环境污染物。目前,正在开发新的先进策略,用于针对由病毒或细菌病原体以及癌症引起的广泛疾病的治疗、诊断和治疗诊断方法。这项工作概述了基于GO的传感系统依靠其荧光猝灭效应的最新应用。
