Graphene-Based electrochemical sensors for detection of environmental pollutants

In recent years, graphene is often used in the design of electrochemical sensors to improve detection sensitivity due to the enormous specific surface area, excellent mechanical flexibility, chemical resistance, and outstanding electrical and thermal conductivity. Graphene-based electrochemical sensors have gained attention due to their monitoring, diagnosis of pollutants in the environment, and promoting rapid, effective, and environmentally friendly processing techniques. In addition, graphene-based electrochemical sensors were discussed with illustrations, limitations, and future directions for electrochemical sensor applications and development for qualitative and quantitative analysis of environmental pollutants, heavy metals, steroid compounds, antibiotic residues, and pesticides.
