The landscape of nanotechnology strategies against Covid-19 : products and diagnostics, vaccines and treatments

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

Potencialidades reflexivas para a formação inicial a partir do PIBID e do Estágio

The aim of this article is to understand the students ‘conceptions about the initial training process experienced in the University from PIBID Program and the supervised training. The focus will not be the comparison of these programs, but the potentialities of each one to a reflection about the teacher training. The data are from questionnaires which were answered by licensed practical students who participate or participated of PIBID and attend or attended the supervised training. The analysis will be done to the light of the bakhtinian dialogic perspective of the language. This referential pointed out that there are, among the students, an idea that in PIBID there is higher contact with the reality of the public school than the training program. This is related to the fact that in PIBID all the actions, since the planning to the intervention are collective. It is suggested, therefore, that the development of teaching abilities is built, by the licensed practical students, for otherness principles.O objetivo do artigo é compreender as concepções dos estudantes sobre o processo formativo inicial vivenciado na Universidade a partir do PIBID e do Estágio Supervisionado. O foco não será a comparação dos programas, mas as potencialidades de cada um para a reflexão sobre a formação docente. Os dados resultam de questionários coletados junto a alguns dos licenciandos que participam ou já participaram do PIBID e cursam ou já cursaram o Estágio. A interpretação será realizada à luz da perspectiva dialógica bakhtiniana da linguagem. Esse referencial revelou que há, entre os estudantes, uma ideia de que no PIBID há maior contato com a realidade da escola pública em detrimento dos estágios. Isso está relacionado ao fato de que no PIBID todas as ações, desde o planejamento até as intervenções são coletivas. Sugere-se, portanto, que a constituição da docência é construída, pelos licenciandos, por princípios de alteridade. El objetivo del artículo es comprender las percepciones de los estudiantes sobre el proceso de formación inicial experimentado en la universidad desde el PIBID y las prácticas supervisadas.

Una carrera contra el tiempo para buscar estrategias para combatir la enfermedad del nuevo coronavirus contribuye a la unión de los científicos de todo el mundo, incluyendo el uso de la nanotecnología. Por lo tanto, el objetivo del estudio fue describir el panorama de las estrategias de la nanotecnología contra COVID-19, destacando principalmente los productos y diagnósticos, vacunas y tratamientos que son o pueden ser utilizados. Se realizó una revisión bibliográfica de los estudios publicados entre febrero y noviembre de 2020 en las bases de datos PubMed, Scielo y Google Scholar. Según los índices de las distintas bases de datos, se utilizaron los términos de búsqueda "new coronavirus 2019", "COVID-19", "severe acute respiratory syndrome" Nanotechnology against COVID-19", "COVID-19 Vaccines" sin ninguna restricción de idioma. El uso de materiales de base nanométrica ha indicado un gran potencial contra la diseminación del COVID-19, con la producción de productos, diagnósticos, vacunas y tratamientos
