Abstract

Laser-induced graphene, which was first reported in 2014, involves the creation of graphene by using a laser to modify a polyimide surface. Since then, laser-induced graphene has been extensively studied for application in different scientific fields. One beneficial approach is the use of laser-induced graphene coupled with electrochemistry, where there is a growing need for disposable, conductive, reproducible, flexible, biocompatible, sustainable, and economical electrodes. In this mini overview, we explore the use of laser-induced graphene as the basis of electroanalytical sensors. We first introduce laser-induced graphene, before moving to the use of laser-induced graphene electrodes highlighting the various approaches and different laser parameters used to produce different graphene micro and macro structures, whilst describing how these structures are characterised and benchmarked for those working in the field of laser-induced graphene electrodes for comparison aspects. Next, we turn to the use of laser-induced graphene electrodes as the basis of electrochemical sensing platforms towards key analytes and its use in the development of biosensors. We provide a critical overview of the use of laser-induced graphene sensors compared to screen-printed and additive manufactured electrodes, providing future suggestions for the field.

电分析概述:利用激光诱导石墨烯传感器。
2014年首次报道的激光诱导石墨烯,涉及到使用激光修饰聚酰亚胺表面来制备石墨烯。从那时起,激光诱导石墨烯在不同的科学领域得到了广泛的应用研究。一种有益的方法是使用激光诱导石墨烯与电化学相结合,其中对一次性、导电、可复制、柔性、生物相容性、可持续和经济的电极的需求日益增长。在这个小型概述中,我们探讨了使用激光诱导石墨烯作为电分析传感器的基础。我们首先介绍了激光诱导石墨烯,然后转移到使用激光诱导石墨烯电极,重点介绍了用于产生不同石墨烯微观和宏观结构的各种方法和不同的激光参数,同时描述了这些结构是如何表征的,并为那些在激光诱导石墨烯电极领域工作的人进行了比较。接下来,我们转向使用激光诱导石墨烯电极作为关键分析物的电化学传感平台的基础及其在生物传感器开发中的应用。我们对激光诱导石墨烯传感器与丝网印刷和添加剂制造电极的使用进行了综述,并为该领域的未来发展提供了建议。
