Abstract
MXene, a novel class of 2-dimensional transition metal carbides has evolved as a promising material for various applications owing to its outstanding characteristics such as hydrophilicity, high electrical conductivity, surface area, and attractive topological structure. MXenes can form dispersion in common solvents and constitute composite with other nanomaterials, which can be utilized as effective transducers for molecular sensing. MXene-modified support materials, thus provide an intriguing platform for immobilization of target molecules onto their surface. The literature reveals that it has been increasingly utilized in the sensing of diverse types of analytes including glucose, pharmaceuticals, metals and dyes, cancer markers, pesticides, neurotransmitters, small valuable molecules, and so on. In this review, we summarize the recent updates in the MXene modified materials for sensing. For the convenience of our audience, we have distributed the analytes into categories and discussed them comprehensively. Not only we present the synthesis approach, electrochemical properties and surface chemistry of MXenes but also discussed briefly the current challenges and an outlook for future research in the related area.

Abstract
Pesticides play an important role in agricultural fields, but the pesticide residues pose strong hazardous to human health, thus designing sensitive and fast method for pesticides monitor is highly urgent. Herein, nanoarchitecture of Mxene/carbon nanohorns/β-cyclodextrin-Metal-organic frameworks (MXene/CNHs/β-CD-MOFs) was exploited as electrochemical sensing platform for carbendazim (CBZ) pesticide determination. β-CD-MOFs combined the properties of host-guest recognition of β-CD and porous structure, high porosity and pore volume of MOFs, enabling high adsorption capacity for CBZ. MXene/CNHs possessed large specific surface area, plenty of available active sites, high conductivity, which afforded more mass transport channels and enhances the mass transfer capacity and catalysis for CBZ. With the synergistic effect of MXene/CNHs and β-CD-MOFs, the MXene/CNHs/β-CD-MOFs electrode extended a wide linear range from 3.0 nM to 10.0 μM and a low limit of detection (LOD) of 1.0 nM (S/N = 3). Additionally, the prepared sensor also demonstrated high selectivity, reproducibility and long-term stability, and satisfactory applicability in tomato samples.
