Advances in Two-Dimensional Materials for Electrochemical Biosensors

Dear Colleagues,

Two-dimensional (2D) materials have attracted much attention in the past decade. They offer a high specific surface area as well as electronic structure and properties that differ from their bulk counterparts due to the low dimensionality. Graphene is the best-known and most-studied 2D material, but metal oxides and hydroxides (including clays), transition metal carbides and nitrides (MXenes), dichalcogenides, boron nitrides (BN), carbon nitrides, monoelemental Xenes (including phosphorene and bismuthene), and other materials that are one or several atoms thick are receiving increasing attention. The specific chemical, physical, and optical properties of 2D materials can influence the performance of bio/sensing, improve drug delivery and photo/thermal therapy and affect their toxicity. Two-dimensional materials have been used in numerous applications and in different fields of research such as biomedicine, biosensing, and chemical sensing as well as energy storage and generation, electronics, etc.

Considering the current strong interest of scientists in the physicochemical properties of 2D materials and the potential for electrochemical and biomedical applications, as well as the challenges faced during practical applications, this Special Issue aims to bring together a wide range of recent original research articles, reviews, and prospective articles on 2D materials in the field of electrochemical biosensing. Focusing on the atomic structure, surface morphology, and physicochemical properties of 2D materials will no doubt reveal the general rules for the enhancement of their electrochemical biosensing performance. This Special Issue will focus on (but is not limited to) the following topics:

• The synthesis, characterization, and biosensing abilities of 2D materials and composites;
• Surface engineering, interface engineering, and defect engineering of 2D materials towards boosting electrochemical biosensing;
• Current challenges and prospects of 2D materials in electrochemical sensing and biosensing devices.
