MXene-Based Chemo-Sensors and Other Sensing Devices

Abstract

MXenes have received worldwide attention across various scientific and technological fields since the first report of the synthesis of Ti3C2 nanostructures in 2011. The unique characteristics of MXenes, such as superior mechanical strength and flexibility, liquid-phase processability, tunable surface functionality, high electrical conductivity, and the ability to customize their properties, have led to the widespread development and exploration of their applications in energy storage, electronics, biomedicine, catalysis, and environmental technologies. The significant growth in publications related to MXenes over the past decade highlights the extensive research interest in this material. One area that has a great potential for improvement through the integration of MXenes is sensor design. Strain sensors, temperature sensors, pressure sensors, biosensors (both optical and electrochemical), gas sensors, and environmental pollution sensors targeted at volatile organic compounds (VOCs) could all gain numerous improvements from the inclusion of MXenes. This report delves into the current research landscape, exploring the advancements in MXene-based chemo-sensor technologies and examining potential future applications across diverse sensor types.

MXene-Based Flexible Electrodes for Electrophysiological Monitoring

“…MXenes have generated significant attention in biomedical research due to their ultrathin structure and intriguing properties, including electronic, optical, magnetic, and others [ 19 , 20 , 21 ]. Belonging to the category of 2D nanomaterials, MXenes consist of early transition metal carbides, carbonitrides, and nitrides, showcasing promising attributes such as high electrical conductivity, strength, flexibility, and volumetric capacitance [ 22 , 23 ]. This study proposes a combination of MXene and PDMS to utilize the attractive electrochemical properties of MXenes while retaining the biocompatibility and inherent flexibility of PDMS.…”
