The Application of Nanozymes in the Diagnosis and Treatment of TUMOR: A Review

Nanozyme is a kind of nanomaterial with simulated enzyme activity. Due to its high catalytic efficiency, better stability and modifiability, the role of nanozymes in medicine, especially in the diagnosis and treatment of tumors, is receiving more and more attention. Nanozymes usually contain metals and are often used in combination with drugs or antigens/antibodies to become multifunctional materials for the diagnosis and treatment of tumors. At present, the detailed synthesis, classification and function of nanozymes need to be supplemented. In our review, we introduce the research status, synthesis and classification of nanozymes roundly. Then we summarized and introduced some characteristic nanozymes according to their functions, mainly including tumor diagnosis, tumor therapy, tumor surgical adjuvant therapy and multifunctional complexes. We believe that many breakthroughs have been made in the research of nanozymes, and more and more multifunctional nanozymes have been studied. However, there are still some shortcomings in the current research on nanozymes such as the lack of solutions to some of the insufficient properties of nanoparticles, like spontaneous aggregation, nonspecific phagocytosis, etc. At the same time, the catalytic reaction is relatively simple, which limits the further application of nanozyme. In our review, we made our own comments and prospects on the diagnostic, therapeutic and application of nanozymes. In the future, nanozymes will play an increasingly important role in the diagnosis and treatment of tumors due to their potential modifiability and versatility as well as their increasingly perfect physicochemical properties.
