The pandemic state, declared by the World Health Organization, on March 11, 2020, has tested society's adaptability and response. A race against time to seek strategies to fight the disease of the new coronavirus contributes to the union of scientists from all over the world, including using nanotechnology Thus, the objective of the study was described the landscape of nanotechnology strategies against COVID-19,highlighting mainly the products and diagnostics, vaccines and treatments that are or can be used. A literature review was carried out in studies published from February to November2020 in PubMed, Scielo, and Google Scholar databases. According to the indexes of the various databases, search terms were used: “new coronavirus 2019”, “COVID-19”, “severe acute respiratory syndrome” Nanotechnology against COVID-19”, “COVID-19 Vaccines” without any language restrictions. The use of nano-based materials has indicated a great potential against dissemination of COVID-19, with the production of products, diagnostics, vaccines and treatments. Our results demonstrate that nanotechnology offers processes, materials and tools that contribute to increase the sensitivity, agility and reliability of the diagnostic, in addition to providing more effective options for prevention, diagnostic and therapies.
