Abstract

Over the past few decades, humankind has constantly encountered new viral species that create havoc in the socioeconomic balance worldwide. Among the method to combat these novel viral infections, fast and point-of-care diagnosis is of prime importance to contain the spreading of viral infections. However, most sensitive diagnostic systems for viral infections are time-consuming and require well-trained professionals, making it difficult for the patients. In recent years nanozymes emerged as promising therapeutic and fast diagnostic tools due to their multienzyme-like catalytic performance. Nanozymes can be designed using inorganic or organic components with tailorable physicochemical surface properties, enabling the attachment of various molecules and species on the surface of the nanozyme for specific recognition. In addition to the composition, the multienzyme-like catalytic performance can be modulated by the shape and size of the nanoparticles. Due to their multicatalytic abilities, nanozymes can be used for fast diagnosis and therapy for viral infections. Here we attempt to focus on the insights and recent explorations on the advances in designing various types of nanozymes as a theranostic tool for viral infections. Thus, this review intends to generate interest in the clinical translation of nanozymes as a theranostic tool for viral infections by providing knowledge about the multidisciplinary potential of nanozyme.
