Abstract
Biosensors using opto electronics mechanisms are evolving as efficient (sensitive and selective) and low-cost analytical diagnostic devices for early-stage disease diagnosis, which is crucial for person-centered health and wellness management. Due to advancements in nanotechnology in
the areas of sensing unit fabrication, device integration, interfacing, packaging, and sensing performance at the point-of-care (POC), personalized diagnostics are now possible, allowing doctors to tailor tests to each patient's unique disease profile and management requirements. Innovative
biosensing technology is being pushed as the diagnostic tool of the future because of its potential to provide accurate results without requiring intrusive procedures. Because of this, this visionary piece of writing explores analytical methods for managing personalised health care that can
enhance the health of the general population. The end goal is to take control of a healthier tomorrow as soon as possible. Right now, the most crucial part of controlling the COVID-19 pandemic, a potentially fatal respiratory viral disease, is the rapid, specific, and sensitive detection of
human beta severe acute respiratory system coronavirus (SARS-CoV-2) protein.
