Covid-19 remains a global pandemic surging with different variants like (Omicron) in various countries. An escalation in random testing for Covid-19 is considered as the golden standard by WHO to control the spread of Corona virus. RT-PCR and nucleic acid hybridization strategies are 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 of a rapid, efficient, low-cost, and easy-to-implement test kits are in imperative need to meet these requirements. Electrochemical sensors are considered as potential and ultrafast point-of-care sensors used as self-testing kits. In this work, we review the 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 of present testing patterns and scope of screen-printed electrochemical sensors modified with different nanomaterials and their advantages is presented.
