Presently, an outbreak of coronavirus is of global concern, as it causes various respiratory problems. It was first detected in December 2019 in China's Wuhan City where various patients got admitted to the hospitals with a symptom of pneumonia. As the number of cases increased, scientists isolated the samples from patients. Initially, it was named as a novel coronavirus (2019-nCoV) and now renamed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This virus spread from Wuhan to other cities of China, and currently it is affecting worldwide. Transmission of this virus occurs from one human to another and spreads through contaminated hands or surfaces. Various researchers are trying to explore the potential role of bioactive compounds from plants and different nanomaterials against this virus. Therefore, in this review, an overview of SARS-CoV-2, preventive measures against this viral infection, potential biocides against this virus, and role of phytochemicals and nanomaterials against this virus have been discussed.
