Incidents of viral epidemics have escalated at an alarming rate during the previous decades. The most recent human coronavirus identified as COVID-19 (SARSCoV- 2) has already spread over the world. These epidemics constrain healthcare systems about employing standard medicines and diagnostic technologies. In this context, the application of nanotechnology provides new prospects for the development of novel techniques in terms of diagnosis, prevention, diagnosis and treatment of COVID-19. This review discusses nanotechnology-based strategies for diagnosis, prevention, and treatment of COVID-19, including nanomaterials for surface sterilization, face masks, personal protective equipment, disinfectants, nanocarrier systems and diagnostic systems for treatments and vaccine development. It presents a viewpoint on how nanotechnology may be utilized to battle against COVID-19.
COVID-19, Nanotechnology, Nanomaterials
It was discovered in December 2019 that COVID-19 is caused by SARS-CoV-2 (the new coronavirus originally discovered in Wuhan, China [1, 2]. An important feature of the virus is its ability to rapidly change in order to adapt to different epidemiological settings . The diagnosis and treatment of people with COVID-19 are complicated by the disease’s heterogeneity, which makes it difficult for medical practitioners to narrow down the underlying cause. All kinds of techniques and approaches are needed to understand the host-pathogen interaction and illness in order to produce successful medications and therapies. By offering vaccinations and carriers based on nanoparticles, nanomedicine has the potential to reduce the disease burden [4, 5]. A range of diseases, including respiratory viruses, papillomavirus, herpes virus and HIV, have been successfully treated with nanotechnology in preclinical investigations. To help with the COVID-19, nanotechnology is a top priority in this situation. The nano-regime encompasses all substances with a diameter less than one micrometre. The virus’s size is identical to that of the nanomaterial, making it efficient in attacking it. Moreover, the tiny size of the nanomaterials allows them to be excellent delivery moieties, facilitating targeted drug and gene delivery and modification, and also enhancing interactions between analyte and sensor i.e. permitting rapid and accurate viral detection [6, 7].
