The rise of the Internet of Things has spurred extensive research on integrating conductive materials into textiles to turn them into sensors, antennas, energy storage devices, and heaters. MXenes, owing to their high electrical conductivity and solution processability, offer an efficient way to add conductivity and electronic functions to textiles through simple dip coating. However, manual development of MXene-coated textiles restricts their quality, quantity, and variety. Here, a versatile automated yarn dip coater tailored for producing continuously high-quality MXene-coated yarns and conducted the most comprehensive MXene-yarn dip coating study to date is developed. Compared to manual methods, the automated coater provides lower resistance, superior uniformity, faster speed, and reduced MXene consumption. It also enables rapid coating parameter optimization, resulting in a thin Ti3C2 coating uniform over a 1 km length on a braided Kevlar yarn while preserving its excellent mechanical properties (over 800 MPa) and adding Joule heating and damage sensing to composites reinforced by the yarns. By dip-coating five different yarns of varying materials, diameters, structures, and chemistries, new insights into MXene-yarn interactions are gained. Thus, the automated dip coating presents ample opportunities for scalable integration of MXenes into a wide range of yarns for diverse functions and applications.
In summary, we designed and built a customized automated yarn dip coater for developing MXene-coated yarns, which can also be used for layer-by-layer coating and application of other nanomaterials.The dip coater enabled acomprehensive parametric study of MXene coating on braided Kevlar yarns and helped find the optimal combinations of MXene concentration, flake size, and drawing speed for strain sensing and Joule heating functions. Our high-throughput dip coater enables the production of a vastlibrary of MXene-functionalized conductive yarns exhibiting diverse physical, electrical, and mechanical properties at low costand high quality. As a result, we anticipate that this developmentwill expedite the research and commercialization of MXene dip-coated yarns for electronic textile applications

Scaling up of the MXene Dip-Coated Yarns production process for smart textiles, wearable electronics and structural monitoring and damage diagnostics. 24th Annual Conference on Material Science, Herceg Novi, Montenegro, September 4-8, 2023
MXenes potential applications include sensors, wound healing materials, and drug delivery systems. A recent study explored how different synthesis methods affect the safety and performance of MXenes. By comparing etching conditions and intercalation strategies, researchers discovered that fine-tuning the surface chemistry of MXenes plays a crucial role in improving biocompatibility. These results provide practical guidelines for developing safer MXenes and bring the field one step closer to real biomedical applications.

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.
