Publication date: Available online 6 December 2019Source: Chinese Chemical LettersAuthor(s): Razium Ali Soomro, Sana Jawaid, Qizhen Zhu, Zaheer Abbas, Bin XuAbstractMXenes have emerged as versatile 2D materials that are already gaining paramount attention in the areas of energy, catalyst, electromagnetic shielding, and sensors. The unique surface chemistry, graphene-like morphology, high hydrophilicity, metal-like conductivity with redox capability identifies MXenes, as an ideal material for surface-related applications. This short review summarizes the most recent reports that discuss the potential application of MXenes and their hybrids as a transducer material for advanced sensors. Based on the nature of transducing signals, the discussion is categorized into three sections, which include electrochemical (bio) sensors, gas sensors, and finally, electro-chemiluminescence & fluorescent sensors. The review provides a concise summary of all the analytical merits obtained subsequent to the use of MXenes, followed by endeavors that have been made to accentuate the future perspective of MXenes in sensor devices.Graphical abstractThe review provides a concise summary of recent works carried in the area of electro-chemical driven sensor systems which particularly utilize MXenes or its derivatives as hybrids or composites to serve as a suitable direct or indirect transducer platform
