description Surface-enhanced Raman spectroscopic (SERS) systems and methods for detecting biomolecules of interest, such as a virus, bacterium, or other infectious agent, are provided. A spectroscopic assay based on surface enhanced Raman scattering (SERS) using a silver nanorod array substrate fabricated by oblique angle deposition has been developed that allows for rapid detection of trace levels of viruses or bacteria with a high degree of sensitivity and specificity. This novel and improved SERS assay can detect minor spectral differences within strains of a single virus type such as respiratory syncytial virus or influenza virus in the presence of biological media. The method provides rapid diagnostics for direct molecular and structural characterization of virus strains and virus gene deletion mutants generating reproducible viral spectra without viral manipulation.
