MXenes Biosensors Ti3C2 Cancer Biomarker

Saurabh Kumar, et al., "Biofunctionalized Two-dimensional Ti3C2 MXenes for Ultrasensitive Detection of Cancer Biomarker". Biosensors and Bioelectronics, 121, 2018, 243. In this work, ultrathin Ti3C2-MXene nanosheets were synthesized by minimally intensive layer delamination methods, and uniformly functionalized with aminosilane (f-Ti3C2-MXene) to provide a covalent binding for the immobilized bio-receptor (anti-CEA) for label free, ultrasensitive detection of cancer biomarker (carcinoembryonic antigen, CEA). The effect of different redox probes on the electrochemical behavior of f-Ti3C2-MXene
