MXenes are a class of 2D transition metal carbides and nitrides (MXT) that have attracted significant interest owing to their remarkable potential in various fields. The unique combination of their excellent electromagnetic, optical, mechanical, and physical properties have extended their applications to the biological realm as well. In particular, their ultra-thin layered structure holds specific promise for diverse biomedical applications. This comprehensive review explores the synthesis methods of MXene composites, alongside the biological and medical design strategies that have been employed for their surface engineering. This review delves into the interplay between these strategies and the resulting properties, biological activities, and unique effects at the nano-bio-interface. Furthermore, the latest advancements in MXene-based biomaterials and medicine are systematically summarized. Further discussion on MXene composites designed for various applications, including biosensors, antimicrobial agents, bioimaging, tissue engineering, and regenerative medicine, are also provided. Finally, with a focus on translating research results into real-world applications, this review addresses the current challenges and exciting future prospects of MXene composite-based biomaterials.

In recent years, MAX phases and their two-dimensional counterparts, MXenes, have emerged as significant subjects of interest in the fields of science and engineering, owing to their varied geometries, compositions, and extensive range of applications. This research employs first-principles calculations to explore the geometrical structures, electronic characteristics, phonon dispersions, dynamic stability, electron-phonon coupling (EPC), and superconducting properties of 27 out-of-plane ordered double transition metal carbides, referred to as o-MAX phases, characterized by the general formula MM'AlC (where M = Nb, Mo, W and M' = Sc, Ti, Zr, Hf, V, Nb, Ta, Mo, W). We have identified 16 superconducting o-MAX phases, with four specific compounds WVAlC, WNbAlC, WTaAlC, and MoNbAlC exhibiting a critical temperature () that surpasses 10 K, representing the highest reported experimentally for MAX phases thus far.

A cost-effective strategy is reported utilizing ionic liquid (IL), 1-hexyl-3-methylimidazolium bisulfate ([HMIM] HSO), to delaminate TiC MXene, thereby enhancing its efficiency in electrocatalyzing tryptophan (Trp) oxidation. The positively charged IL effectively intercalates within the negatively charged MXene layers, fostering structural stability through π-π stacking and electrostatic interactions. Consequently, the resulting IL-TiC composite not only maintained the inherent electronic conductivity of TiC but also significantly augmented its electrocatalytic prowess.

In this study, a novel In₂S₃/MXene composite was developed as a co-reactant accelerator to enhance the chemiluminescence (CL) performance of the classical luminol-H₂O₂ system. The In₂S₃ and MXene heterojunction catalyzed the CL reaction through synergistic effect, facilitating the generation of reactive oxygen species and increasing CL intensities. This enhanced system was applied for the first time to detect an ultraviolet (UV) filter-benzophenone-3 (BP-3) by leveraging its light absorption property.

MXenes, as a novel two-dimensional lamellar material, has attracted much attention. However, MXenes lamellar are prone to collapse and stacking under hydrogen bonding and interlayer van der Waals forces, which affects their electrochemical and capacitive deionization performance. A three-dimensional Ni-1,3,5-benzenetricarboxylate/TiCT (Ni-BTC/TiCT) composite electrode material was developed to enhance the electrochemical and capacitive deionization performance.
