Abstract

The COVID-19 pandemic has placed the world in a tailspin. The limited availability of tests was the major challenge in controlling the COVID-19 spread. The gold standard technique for COVID-19 diagnosis is a time-consuming, and laborious process which must be conducted by an expert. The holy grail of controlling a pandemic of this magnitude is to create a rapid, cheap, and easily deployable test for COVID-19. Towards this goal, my research focuses on the development of a rapid (<5 min) molecular test for COVID-19 diagnosis. The test’s performance is comparable with PCR (the gold standard technique) in terms of sensitivity. However, it can be fully automated to be performed by a layperson in minutes. Our test utilizes an ultrasensitive hyperspectral-based nanosensor for the diagnosis of COVID-19. We also show that our sensor can be rapidly modified to detect other viruses such as influenza A H1N1. The outstanding sensitivity indicates the potential of the current biosensor in detecting the prevailing pre-symptomatic and asymptomatic COVID-19 cases. The image submitted here was captured using dark-field hyperspectral imaging microscopy and it is a representation of the changes in the nanomaterial's assembly in the presence (bottom right) or absence (top left) of the SARS-CoV-2 virus.
