2-Dimensional transition metal carbides and nitrides (MXenes) - discovered at Drexel University [1] hold tremendous potential as new materials for biomedial applications. MXenes are produced by selective etching of the A elements (mostly Al) from their ternary layered 3D Mn+1AXn, phase counterparts, where M is an early transition metal, A is an A-group element, X is C and/or N, and n = 1 to 3 [2]. In contrast to raw Mn+1AXn phases, the MXene sheets are oxygenated (═O, −OH) and fluorinated (–F) for preferential sorption of target biomolecules. Beyond the characteristics shared by all 2D materials, MXenes stand out in several ways. They are: i) conductive, with high density of states at the Fermi level and metal-like carrier densities; ii) hydrophilic, and thus processable in eco-friendly and sustainable ways; iii) extraordinarily and readily tailorable at multiple levels. MXenes have already shown promising performance in many applications includingdrug delivery and photothermal therapy [3], antibacterial activity [4], electrodes and sensors for medicine [5, 6],selective sorption of small molecules such as urea removal in wearable dialysis systems [7]. Moreover, cytotoxic tests show no significant effect on cell viability during 24 h incubation with 3T3 fibroblast cells by the titanium carbide MXenes [7]. This kind of MXenes sorbents offer open accessible surfaces fully available for proteins and can also be used in treatment of a broad range of conditions ranging from radiation disease and drug overdose to Ebola, Crohn’s disease, Ankylosing Spondylitis and other conditions related to cytokines or toxin in blood.
