Laser-Scribed Graphene-Based Electrochemical Sensors: A Review

Laser scribing is a technique that converts carbon-rich precursors into 3D-graphene nanomaterial via direct, single-step, and maskless laser writing in environmental conditions using scalable approach. It allows simple, fast, reagentless production of promising material with outstanding physicochemical features to create novel electrochemical sensors biosensors. This review addresses different strategies for fabricating laser-scribed graphene (LSG) devices their association nanomaterials, polymers, biological molecules. We provide an overview applications health monitoring, food safety, clinical diagnosis. The advantages integration machine learning models achieve low bias enhance accuracy data analysis also addressed. Finally, this our insights current challenges perspectives LSG are presented.
