Nanozymes: advance enzyme-mimicking theragnostic tool: a review

Nanotechnology is an emerging area of science that deals with making and designing of nanosized objects having widespread applications. Nanomaterials or nanosized objects have that have at least one dimension in the nanoscale range. Nanozymes are enzymes or nanomaterials showing enzyme-like properties. Nanozymes have similar advantages that are associated with other nanomaterials, too. Nanozymes have combined properties of nanomaterials as well as enzymes, they are capable of leading innovations in science and medicine, and their utility has been demonstrated by the emergence of large number of nanotechnology-based products in the modern scenario for disease prevention and diagnosis. Many of the products utilize enzyme-mimicking properties of the nanozymes besides their other properties. But they do have their limitations and disadvantages. The present review focuses on the diverse potential uses of this newly identified group of enzymes with specific reference to their applications in tackling various aspects of coronavirus disease 2019 (COVID-19).
