| Summary: | MXenes are hydrophilic, conductive, tunable, and biocompatible two-dimensional ceramic materials prepared by etching the 'A' layer from their precursor MAX phases. Although MXenes show exceptional promise in photothermal therapy, biosensing, and regenerative medicine, they face challenges such as oxidative instability in physiological environments, limited drug-loading capacity, and unpredictable immune responses. To address these limitations, MXene/polymer nanocomposites incorporating both synthetic polymers (e.g., polyethylene glycol (PEG), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), and polylactic-co-glycolic acid (PLGA)) and natural biopolymers (e.g., cellulose nanofiber, gelatin, chitosan, hyaluronic acid, and soybean phospholipids) have been developed. These composites enhance functionality for biomedical applications such as photothermal cancer therapy, biosensors, antibacterial agents, bone regeneration, and targeted drug delivery. The hydrophilic nature of MXenes makes them suitable for transformation into metallic-conductive electrodes, while their compatibility with metals, ceramics, and polymers improves performance in advanced applications. This review paper discusses the properties, synthesis methods, and biomedical applications of MXene/polymer nanocomposites, emphasizing the roles of both synthetic and natural biopolymers. Key achievements include near-infrared (NIR) absorption for efficient drug delivery, anticancer activity, bioimaging, and antimicrobial effects. In addition, the limitations of these nanocomposites and potential solutions are examined. |
