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.
