Emerging piezocatalysts have demonstrated their remarkable application potential in diverse medical fields. In addition to their ultrahigh catalytic activities, their inherent and unique charge-carrier-releasing properties can be used to initiate various redox catalytic reactions, displaying bright prospects for future medical applications. Triggered by mechanical energy, piezocatalytic materials can release electrons/holes, catalyze redox reactions of substrates, or intervene in biological processes to promote the production of effector molecules for medical purposes, such as decontamination, sterilization, and therapy. Such a medical application of piezocatalysis is termed as piezocatalytic medicine (PCM) herein. To pioneer novel medical technologies, especially therapeutic modalities, this review provides an overview of the state-of-the-art research progress in piezocatalytic medicine. First, the principle of piezocatalysis and the preparation methodologies of piezoelectric materials are introduced. Then, a comprehensive summary of the medical applications of piezocatalytic materials in tumor treatment, antisepsis, organic degradation, tissue repair and regeneration, and biosensing is provided. Finally, the main challenges and future perspectives in piezocatalytic medicine are discussed and proposed, expecting to fuel the development of this emerging scientific discipline.

“…(e.g., C 3 N 4 11 and GaN 12 ), and transition metal dichalcogenides (TMDs). [13][14][15] . Nevertheless, these inorganic semiconductors suffer from limited structural tailorability, small surface area, and relatively long transport distance of the generated charge carriers, which greatly impedes their piezocatalytic efficiency.…”

Compared with natural enzymes, nanozymes have advantages such as high stability, low cost, and a broad application prospect. However, due to the low catalytic activity of conventional nanozymes, synthesizing nanozymes with excellent enzyme-like activity will be long-term work. Herein, we synthesized single-atom nanozymes centered on Mn with N, P, and S doped (Mn-SAzyme) with enhanced peroxidase-like (POD-like) activity. We found that the presence of the Mn metal center significantly increased the POD-like activity of the nanozyme, exhibiting catalytic properties consistent with Michaelis–Menten kinetics. The POD-like activity was measured to be 17.48 U/mg, which was higher than that of the sample without the metal center. Using methylene blue (MB) as the organic dye model, the degradation efficiency of Mn-SAzyme could reach 90.1% within 300 min at pH 6.5, within the H2O2 concentration of 0.1 M and 25 mg/L of nanozyme dosage. Free radical quenching experiments and electron paramagnetic resonance tests showed that •O2 – and •OH were the key to degrading organic dyes. This work aims to explore more methods for synthesizing highly active nanozymes and successfully applying the synthesized nanozymes to the degradation of organic dyes.
