Direct and label‐free detection of unmodified DNA has always been a great challenge for DNA analyses. Surface‐enhanced Raman spectroscopy (SERS) can provide structural fingerprinting of analytes with single‐molecules sensitivity, so it could be the best candidate for label‐free detection of DNA. Wild mushrooms, a very nutritious and delicious food in our lives, are widely distributed in Yunnan province...
The primary challenge of spectroscopic techniques in selective detection and characterization of tautomeric structures of DNA and RNA bases, and moreover, the accurate interpretation and explanation of the experimental results are the main motives of theoretical studies. Surface‐enhanced Raman spectroscopy (SERS) can be a powerful approach to distinguish cytosine in the presence of its tautomers....
