MXenes have shown exceptional electrochemical properties and demonstrate great promise in chemiresistive gas analysis applications. However, their sensing applications still face low sensitivity specificity, slow response, poor stability among the many challenges. Herein, a novel synthetic approach is reported to produce single-atom Pt (Pt SA)-implanted Ti3C2Tx MXene nanosheets as channel field-effect transistor (FET) sensors. This pioneer study of catalysts loaded on for detection, which demonstrates that SA can greatly enhance performance pristine Ti3C2Tx. The SA-Ti3C2Tx sensor exhibits high specificity toward ppb level (a detection limit 14 ppb) triethylamine (TEA) with good multicycle performance. Moreover, mechanism density functional theory (DFT) simulation show chemical sensitization effect TEA adsorption enhancement from highly catalytic uniformly distributed lead enhanced performances. work presents new prospect applications, will promote development cutting-edge techniques public health environment.

Abstract Black phosphorus nanostructures (nano‐BPs) include BP nanosheets, quantum dots, and nanoparticles. Since first being discovered in 2014, nano‐BP has become one of the most popular nanomaterials. Nano‐BP many unique properties, such as excellent surface activity, tunable bandgap, high carrier mobility, moderate on/off ratio, biocompatibility, good biodegradation, etc., all which make particularly attractive biomedicine biosensing. This review article comprehensively summarizes recent advances synthesis, functionalization, biomedicine, biosensing applications nano‐BP. Different methods are introduced, mechanical cleavage, liquid‐phase ultrasonic exfoliation, electrochemical solvothermal treatment, acoustic‐microfluidic stripping, for making Then two strategies emphasized to enhance ambient stability nano‐BP, namely physical encapsulation chemical modification. Next, how develop advanced imaging agents, nanocarriers, nanomedicine bioimaging (fluorescence imaging, thermal photoacoustic imaging) disease treatment (phototherapy photo/chemical/immune synergistic therapy) is demonstrated. The on including biosensor, fluorescence chemiluminescence electrogenerated colorimetric biosensor. Finally, current challenges future perspectives bioapplications discussed.
