Catalytic nanomedicine, especially artificial enzymes, exhibit obvious merits over traditional nanomedicine. However, the lack of controllability over an enzymatic process seriously challenges the therapeutic performance. Herein, we present a concept of using piezoelectric enzymes in combination with biocomputation ability. As a paradigm, MnTiO3 nanodisks were prepared with multiple enzyme-mimicking activity, including glutathione oxidase, peroxidase, and catalase. Different from the conventional artificial enzymes, the enzymatic activity of Mn...
