This simple and efficient tool can be used in nucleic acid detection, which is helpful in clinical diagnostics for a wide range of conditions, including cancer, genetic diseases, and infectious diseases like anthrax, chlamydia and gonorrhea. It is also capable of identifying genetic markers associated with an increased risk of cancer.
The SERS nanobiosensor developed by the researcher could even detect single molecules with a limit of detection of ~ 0.1 nM and exhibits high specificity for single nucleotide mismatch discrimination. This new technology will help provide earlier, more accurate treatments for a very large number of diseases and conditions.
