Abstract

What level of scientific knowledge has been gained against COVID-19 during the months of the pandemic? Are current technologies able to keep up with the advances in virology research? Historically, disease outbreaks due to pathogenic microorganisms have killed many more people than wars have, and the ability that viral genes have displayed to rapidly change and adapt has forced new studies. Early detection is most important for timely management of any biological attack, whether natural or intentional, and rapid detection systems are essential to counter the effects of viral disease. Optical sensors have several advantages in this field, such as simple and label-free protocols. In this letter, the role of layer materials, such as graphene, is presented. Graphene has unique and excellent optical properties for plasmonics and Raman scattering. Finally, a method of Covid-19 detection on graphene sensors is proposed via a plasmon-molecular orbital interaction that provides a unique signature of the S-protein of the virus.
