Abstract
The family of two-dimensional (2D) transition metal carbides and nitrides, MXenes, has been expanding rapidly since the discovery of Ti3C2 MXene in 2011 [1]. More than 20 different MXenes have been synthesized, and the structure and properties of numerous other MXenes have been predicted using density functional theory calculations [2].
Two-dimensional (2D) materials with a thickness of a few nanometers or less can be used as single sheets due to their unique properties or as building blocks, to assemble a variety of structures. MXenes properties can be tunable for a large variety of applications [3]that directly lead to their use for electromagnetic shielding [4], transparent conductors, light-to-heat energy conversion, new advanced lasers and photothermal therapy.
Synthesis of MXene typically begins with etching the A-element atomic layers (for example, aluminum) in a MAX phase (for example, Ti3AlC2) with HF solution and/or a mixture of fluoride salts and acids at room temperature or slightly higher temperature. After the etching is finished (complete removal of the A-element layers), washing must be applied to remove residual acid and reaction products (salts) and achieve a safe pH (∼6). After the pH is increased to ∼6, and eventual intercalation of large organic molecules and subsequent delamination completed, the multilayered MXene flakes or single nanosheets can be collected via vacuum-assisted filtration and then dried in vacuum [5].
MXenes can be deposited form solution by spin, spray, or dip coating, painted or printed, or fabricated in a variety of ways. Synthesis conditions used to produce MXenes influence the resulting properties and thus are directly related to the performance of MXenes in their applications [5]. In the laboratory, researchers synthesize MXene in gram quantities, and it is very difficult to repeat the synthesis conditions in order to obtain a material with the same repeatable properties.
For scaling up the laboratory process and to obtain material in larger quantities (up to 200 g per batch) of good quality with repeatable properties, a pilot laboratory line was developed [5]), which allows us to control the etching process and adjust its basic parameters - temperature, mixing speed, recording and storing all necessary data for analysis or to repeat the conditions during subsequent syntheses to obtain a MXene with repeatable properties. In addition, since the acidic etching process is accompanied by the release of heat, a specially developed sealed reactor allows safe and reliable synthesis. The computer control system provides the desired precursor feed rate and the optimal synthesis temperature profile [6].

Together with colleagues from the University of Latvia, MRC/Carbone Ukraine, Adam Mickiewicz University, University Clinic Essen, and others, we have developed a novel concept involving the binding of antibodies to MXenes. In our research, we utilized anti-CEACAM1 antibodies to develop targeted photo-thermal therapy for melanoma (in vitro), paving the way for future in vivo studies and clinical trials. For the first time, we demonstrate the feasibility of delivering MXenes specifically targeted to melanoma cells, enabling the effective ablation of cancer cells under near-infrared (NIR) light. This new technique opens up vast potential for the application of MXenes in cancer treatment, diagnostics, drug delivery, and many other medical purposes.
Here we demonstrate a new developed method for depositing Ti3C2Tx MXenes onto hydrophobic electrospun PCL membranes using oxygen plasma treatment. These novel patches hold tremendous potential for providing mechanical support to damaged heart tissue and enabling electrical signal transmission,thereby mimicking the crucial electroconductivity required for normal cardiac function. After a detailed investigation of scaffold-to-cell interplay, including electrical stimulation, novel technology has the potential for clinical application not only for cardiac regeneration, but also as neural and muscular tissue substitutes.
