Unleashing the potential of tungsten disulfide: Current trends in biosensing and nanomedicine applications

“…For decades, electrochemical biosensors-based screen-printed electrodes and semiconductors compounds were massively studied and implicated for numerous applications in multiple fields [ [131] , [132] , [133] , [134] , [135] , [136] ]. TMDCs incorporation into the electrochemical sensing interface has led to the development of novel biosensors with more favorable and enhanced performances [ 137 ].…”

DNA-Coupled AuNPs@CuMOF for Sensitive Electrochemical Detection of Carcinoembryonic Antigen

“…To date, electrochemical immunoassay has attracted tremendous attention as a promising candidate, considering its high sensitivity, selectivity, portability, and simplicity at cost-effectiveness. − However, the efficiency of such immunosensors strongly depends on how the recognition probes are tethered to the sensing surface. − In other words, the control of capture probe orientation and density streamlines its binding activity with the targets, affecting the stability and sensitivity of the biosensors. Addressing this controversy, three-dimensional tetrahedron DNA structured probes (3D TDNA) were introduced as a new type of DNA structure, providing exceptional mechanical robustness and structural stability. − On the other hand, altering the sensing surface using multiple technologies involving nanomaterial functionalization plays a pivotal role in yielding higher biocompatibility and electron conductivity while mitigating surface fouling.…”
