Emerging Spectroscopy Techniques for Detection of Coronavirus (COVID-19): A Review

Author : Reha Panigrahi and Nazar Hussain

With the coronavirus pandemic (COVID-19) global outbreak in December 2019 and its unprecedented impact on society, health, and economy, it has become imperative to detect it earliest and prevent further escalation. At present, there have already been several detection techniques, including rapid antigen or antibody tests, immunoenzymatically serological tests, and molecular qRT-PCR tests, are widely used. Although these are exceptionally reliable diagnostic methods for the diagnosis of COVID- 19 effectively and accurately, all these techniques have some limitations. Therefore, intensive research is going on for the instant, specific and sensitive detection of COVID-19 using a varied approach. There has been a growing interest in spectroscopic techniques to use as a biomedical tool for the early diagnosis and monitoring of COVID-19. In this review article, apart from these conventional methods, we have summarized recently developed spectroscopy techniques to detect COVID-19.
