Abstract
Electrochemical sensors are a useful tool for healthcare monitoring in real time. The continuous progress in nanomaterial synthesis leads to further improvement on catalytic properties of sensing platforms. Tremendous recent efforts have been made in design of novel sensing platforms with two-and three-dimensional nanocomposites using variety of materials like MXene, graphitic boron nitride (h-BN), metal-organic frameworks (MOFs) and transition metal dichalcogenides (TMD). The functionalization of nanomaterials provides even more high analytical performance of sensors which extends their application in environmental monitoring. The paper highlights the recent progress in designing micro-tools with variety of shapes and flexible structures for biomedical and healthcare applications and recent advancements in functionalizing 2D and 3D nanomaterials for electrochemical sensing applications are discussed. The discussion was extended to cover the main challenges in printing strategies to get wearable and flexible sensors with the emphasis on innovative methods and fast experimental protocols, highlighting even more the effect of electroanalytical parameters on the performance of sensors.
