Post reporting of deadly virus infecting mankind in city of Wuhan (China) major changes in socio-economic conditions have been encountered. Being reported on 31st December 2019, later named Covid-19 disease has been declared global pandemic on March 11th, 2020 by WHO. Assuming 40-60% people of entire world might get affected due to this virus, lockdown was imposed as an immediate action. This was to curtail transmission of virus through physical contact. This lockdown has shown significant impact on air pollution on a global scale which needs to be analysed for further requirements. It is a known fact that air pollution impacts human respiratory system. Hence analysis of particulate matter and air pollutants post-lockdown and pre-lockdown during Covid pandemic may yield significant results. Even though treatment and prevention of Covid-19 is a big challenge right now, role of nanotechnology should not be ignored. Since nanotechnology is a multidisciplinary and focused field, it is capable of pivoting solutions for problems posed due to this virus and could relieve the excess strained hospitals. Since Covid-19 work on a nanoscale idea of using nanotechnology may offer significant results in the biomedical field that include both diagnostic and therapeutic approaches. In this context an attempt was made to review some of the published results related to the nature of virus and role of nano and microparticles on Covid-19 as well as to analyse particulate matter and air pollutants for a coastal, urban, industrial station in Visakhapatnam India.
