Abstract
The upgrading of useful biosensors having advantages in disease monitoring besides detection has been sped up by the demand for quick, cheap, portable, easy screening procedures. Bioanalytical devices such as Biosensors have a number of distinguishing benefits over conventional analytical techniques, including high accuracy and specificity, ease of handling, economic friendly, and the potential for downsizing and mass production. With an emphasis on electrochemical and optical sensors, this study examines current developments in the design, performance, and applications of biosensors. Due to its advantages of high sensitivity, specificity, and rapid analysis, electrochemical sensors have demonstrated a wide range of applications in biological detection whereas the optical biosensors covered in this article have enabled diagnosis of SARS-CoV-2, which highlighted the importance of creating swift and extremely sensitive diagnostic methods for quickly identifying infected patients using LSPR, SERS, FET, EC biosensors.
