BIOPLASMONIC DETECTION OF BIOMARKERS IN BODY FLUIDS USING PEPTIDE RECOGNITION ELEMENTS

摘要

Plasmonic nanotransducers and methods for label-free detection of biomarkers are disclosed. The plasmonic nanotransducers include nanostructure cores and peptide aptamers. The plasmonic nanotransducers are exposed to a biological sample that can contain the specific biomarkers and can be analyzed with surface enhanced Raman scattering techniques and/or localized surface plasmon resonance techniques to quantify the amount of the biomarker in the sample.
