A method for detecting dust mite antigens includes the steps of collecting a dust sample, applying an extraction and cleanup procedure for dust mite antigens from the dust sample in order to obtain a sample solution ready for measurement, and placing the sample solution on a SERS chip without immunological modification and under a Raman spectrometer for SERS detection in order to identify whether any dust mite antigens exist in the sample solution.

System and method for detection of dust mite antigens

A surface-enhanced Raman scattering (SERS) detection method is provided for detecting a target analyte in a sample. The SERS detection method generally includes the steps of: (a). preparing an extract of the sample; (b). introducing the sample extract onto a SERS substrate, causing the target analyte to be absorbed in the SERS substrate; (c). introducing a volatile organic solvent onto the SERS substrate to have the target analyte of the sample extract dissolved and comes out of the SERS substrate; (d). irradiating the SERS substrate with light to evaporate the volatile organic solvent, leaving a more condensed target analyte on the SERS substrate; (e). irradiating the condensed target analyte with laser light to have the target analyte penetrate deeply into the SERS substrate; and (f). performing Raman measurement with a laser beam focusing on the SERS substrate to analyze the target analyte.

Surface-enhanced Raman scattering detection method for rapid detection of pesticide residues

Disclosed herein describes an SERS sensing substrate comprising upright metal nanostructures made by using oblique angle deposition (OAD) collocating with self-rotation substrate, wherein said upright nanostructures include individual upright nanopillars and metal/dielectric multilayered upright nanopillar stacks. The SERS sensing substrate exhibits higher and enhanced adsorption spectra for unpolarized incident rays in the visible and infrared wavelength regimes.
