Nanozymes
constitute an emerging class of nanomaterials
with enzyme-like
characteristics. Over the past 15 years, more than 1200 nanozymes
have been developed, and they have demonstrated promising potentials
in broad applications. With the diversification and complexity of
its applications, traditional empirical and trial-and-error design
strategies no longer meet the requirements for efficient nanozyme
design. Thanks to the rapid development of computational chemistry
and artificial intelligence technologies, first-principles methods
and machine-learning algorithms are gradually being adopted as a more
efficient and easier means to assist nanozyme design. This review
focuses on the potential elementary reaction mechanisms in the rational
design of nanozymes, including peroxidase (POD)-, oxidase (OXD)-,
catalase (CAT)-, superoxide dismutase (SOD)-, and hydrolase (HYL)-like
nanozymes. The activity descriptors are introduced, with the aim of
providing further guidelines for nanozyme active material screening.
The computing- and data-driven approaches are thoroughly reviewed
to give a proposal on how to proceed with the next-generation paradigm
rational design. At the end of this review, personal perspectives
on the prospects and challenges of the rational design of nanozymes
are put forward, hoping to promote the further development of nanozymes
toward superior application performance in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
