| Plasmonic biosensors |
Many clinically relevant analytes may be detected using these biosensors, which are label-free and extremely sensitive. Human serum samples can be used directly for the detection of nucleocapsid antibodies (specific to SARS-CoV-2) using a SPR biosensor. |

| Field-effect transistor (FET)-based biosensing |
A number of anticipated benefits of FET-based biosensors include the ability to be very sensitive and detect tiny amounts of target analyte immediately. Clinical analysis, point-of-care testing, and on-site diagnostics all have the ability to revolutionize from these biosensors. |

| Electro-chemical biosensors |
For its high sensitivity/specificity, simplicity, low cost, ease of use and ability to be miniaturised and bulk produced in large quantities, electrochemical biosensors are popular among researchers. These biosensors can also be used in homes and clinics because of their point-of-care (POC) capabilities. |

| Surface-enhanced Raman scattering (SERS)-based biosensors |
Scientists employ these biosensors due to their ability to detect analytes with remarkable sensitivity and precision utilising SERS-encoded nanoparticles (SERS tags) instead of colloidal gold. The adsorbed Raman reporter dyes, the gold/silver nanoparticle substrates, and the exact antibodies that attach to their respective targets—these are the main components of SERS tags. |
