To manage the COVID-19 pandemic, development of rapid, selective,
sensitive diagnostic systems for early stage β-coronavirus
severe acute respiratory syndrome (SARS-CoV-2) virus protein
detection is emerging as a necessary response to generate the
bioinformatics needed for efficient smart diagnostics,
optimization of therapy, and investigation of therapies of
higher efficacy. The urgent need for such diagnostic systems is
recommended by experts in order to achieve the mass and targeted
SARS-CoV-2 detection required to manage the COVID-19 pandemic
through the understanding of infection progression and timely
therapy decisions. To achieve these tasks, there is a scope for
developing smart sensors to rapidly and selectively detect
SARS-CoV-2 protein at the picomolar level. COVID-19 infection,
due to human-to-human transmission, demands diagnostics at the
point-of-care (POC) without the need of experienced labor and
sophisticated laboratories. Keeping the above-mentioned
considerations, we propose to explore the compartmentalization
approach by designing and developing nanoenabled miniaturized
electrochemical biosensors to detect SARS-CoV-2 virus at the
site of the epidemic as the best way to manage the pandemic.
Such COVID-19 diagnostics approach based on a POC sensing
technology can be interfaced with the Internet of things and
artificial intelligence (AI) techniques (such as machine
learning and deep learning for diagnostics) for investigating
useful informatics via data storage, sharing, and analytics.
Keeping COVID-19 management related challenges and aspects under
consideration, our work in this review presents a collective
approach involving electrochemical SARS-CoV-2 biosensing
supported by AI to generate the bioinformatics needed for early
stage COVID-19 diagnosis, correlation of viral load with
pathogenesis, understanding of pandemic progression, therapy
optimization, POC diagnostics, and diseases management in a
personalized manner.
