Minireview: Recent Advances in Surface-Enhanced Raman Scattering-Based Nucleic Acid Detection with Application to Pathogen Diagnosis

摘要

Surface-enhanced Raman scattering (SERS) is a promising analytical tool in nanoscale detection because of its high sensitivity and selectivity. This review focuses on recent advances in SERS-based detection of DNA and RNA. First, nanostructure-based SERS-active substrates are introduced. Using label-free and labeled SERS, target biomolecules such DNA, RNA and microRNA have been successfully detected. Finally, applications in pathogen diagnosis are discussed. The prospects and challenges of SERS-based bioanalysis are highlighted.
