Abstract

Abstract : Covid-19 still remains as global pandemic surging with different variants like alpha, beta, gamma, delta and most omicronin various countries resulted into SARS-CoV-2. An escalation in random testing for Covid-19 is considered as golden standard by World Health Organization (WHO) to control the spread of Corona virus. RT-PCR and nucleic acid hybridization strategies are the two highly sensitive outstanding tests used for the detection of SARS-CoV-2 in the DNA by the former and RNA/DNA by the later. Apart from the test for virus, antigen and antibodies other alternative hematological tests like CRP, Ferritine, IL-6, Blood Platelets and WBC and plasma became essential for the detection and management of Covid-19. Overcoming the limitations a rapid, efficient, low-cost and easy-to-implement test kits are in imperative need to meet the requirement. Electrochemical sensors are considered as potential, ultra-fast and point-of-care sensors used as self-testing kits. In this work, a meta review of various modified electrodes with different nanomaterials such as graphene, CNTs, and nano-dopants used as electrochemical sensors in association with testing various different parameters for detection of Covid-19. A detailed discussion on the merits and demerits of present testing patterns and scope of screen-printed electrochemical sensors modified with different nanomaterials and their advantages are presented.
