The scientific journal «Applied Physics Reviews» published a study titled “Fast, accurate, point-of-care COVID-19 pandemic diagnosis enabled through advanced lab-on-chip optical biosensors: Opportunities and Challenges” (https://aip.scitation.org/doi/10.1063/5.0022211) in which researchers from the University of Texas and Omega Optics Inc. developed optical biosensors and were able to quickly detect Covid-19.
Their technique was since when a virion (whole particle of the virus) is on the surface of an optical sensor, the light beam in the sensor is affected by the particle and the signal given by the light is displaced.
According to this technique, even if the dose of the virus is very small, the system can detect Covid-19 with great success in real time.
Utilization of this technique, in addition to the continuous improvement of the technical possibility, by their integration in measurements of plasma oscillations or the integration of graphene in the process of its preparation, in workplaces, in emergency hospitals, in schools / universities and educational institutions.
