MXenes: 2D Materials that Can Reach Far beyond Graphene
Dr. Yury Gogotsi
Department of Materials Science and Engineering, and A. J. Drexel Nanomaterials Institute, Drexel University, Philadelphia, PA 19104, USAAbstract:
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. Graphene is the best-known example, but several other elemental 2D materials (silicene, borophene, etc.) have been discovered. Numerous compounds, ranging from clays to BN and transition metal dichalcogenides, have been produced as 2D sheets. By combining various 2D materials, unique combinations of properties, which are not available in any bulk materials, can be achieved. The family of two-dimensional (2D) transition metal carbides and nitrides, MXenes, has been expanding rapidly since the discovery of Ti3C2 in 2011 [1]. About 30 different MXenes have been synthesized, and the structure and properties of numerous other MXenes have been predicted using density functional theory calculations [2]. The availability of solid solutions on M and X sites, control of surface terminations, and a recent discovery of multi-element layered MXenes (e.g., Mo2TiC2) offer a potential for synthesis of dozens of new distinct structures. MXenes’ versatile chemistry renders their properties tunable for a large variety of applications. Oxygen or OH terminated MXenes, such as Ti3C2O2, have redox capable transition metals layers on the surface and offer a combination of high electronic conductivity with hydrophilicity, as well fast ionic transport. This makes them promising candidates for energy storage and related electrochemical applications, but their applications in optoelectronics, electromagnetic interference shielding, plasmonics, sensors, water purification and desalination, electrocatalysis, medicine and other fields are equally exciting [2].

Congratulations and thank you to our collaborators from TU Wien and CEST for very interesting work and making it published! In this work, an upscalable electrochemical MXene synthesis is presented. Yields of up to 60% electrochemical MXene (EC-MXene) with no byproducts from a single exfoliation cycle are achieved.
Thank you to our collaborators for the amazing joint work recently published in Graphene and 2D Nanomaterials about MXene–silk fibroin composite films aiming to develop materials with tunable electronic and thermal properties
Congratulations to all collaborators with this interesting joint work!
Dr. Oleksiy Gogotsi, director of MRC and Carbon-Ukraine, innovative companies that are among the leaders on the world MXene market, visited 2024 MRS Fall Meeting & Exhibit. together with Dr. Maksym Pogorielov, Head of Advanced Biomaterials and Biophysics Laboratory, University of Latvia.
MRC and Carbon-Ukraine team visited the 3rd International MXene conference held at Drexel University on August 5-8, 2024. Conference brought together the best reserchers and leading experts on MXene field. 
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.
MX-MAP project participants from MRC Dr. Oleksiy Gogotsi and Veronika Zahorodna performed split secondment visit to project partner organization University of Padova (Italy). MX-MAP project works on development of the key strategies for MXene medical applications. 
CanbioSe Project Meeting and Project Workshop was held at European Institute of Membranes (IEM), University of Montpellier, France on September 26-27, 2023. The workshop was focused on the theme of "Commercializing Biosensors, Intellectual Property, and Knowledge Transfer from Academia to Industry.
Dr. Oleksiy Gogotsi and Veronika Zahorodna visited IEEE NAP 2023 conference held in Bratislava on September 10-15, 2023. The prime focus of the IEEE NAP-2023 was on nanoscale materials with emphasis on interdisciplinary research exploring and exploiting their unique physical and chemical proprieties for practical applications.
Director of MRC and Carbon-Ukraine Dr. Oleksiy Gogotsi visited CEST labs in Wiener Neustadt (Low Energy Ion Scattering, Batteries development) and TU Vienna (ELSA, SFA). He meet with Dr. Pierluigi Bilotto, Dr. Chriatian Pichler and their colleagues, discussing novel materials and r&d activities for new technologies.
