{Reference Type}: Journal Article {Title}: Progress and Insights in the Application of MXenes as New 2D Nano-Materials Suitable for Biosensors and Biofuel Cell Design. {Author}: Ramanavicius S;Ramanavicius A; {Journal}: Int J Mol Sci {Volume}: 21 {Issue}: 23 {Year}: Dec 2020 3 {Factor}: 6.208 {DOI}: 10.3390/ijms21239224 {Abstract}: Recent progress in the application of new 2D-materials-MXenes-in the design of biosensors, biofuel cells and bioelectronics is overviewed and some advances in this area are foreseen. Recent developments in the formation of a relatively new class of 2D metallically conducting MXenes opens a new avenue for the design of conducting composites with metallic conductivity and advanced sensing properties. Advantageous properties of MXenes suitable for biosensing applications are discussed. Frontiers and new insights in the area of application of MXenes in sensorics, biosensorics and in the design of some wearable electronic devices are outlined. Some disadvantages and challenges in the application of MXene based structures are critically discussed.
