Abstract:
1. An analyte detection system, comprising: a lateral-flow chromatographic assay cassette that includes a surface configured to detect an analyte in a sample; an illuminating light source positioned and configured to illuminate the surface of the lateral-flow chromatographic assay cassette with at least one wavelength of light in order to yield an elastic light scattering signal in response to the presence of the analyte; a detector device positioned to capture and detect the elastic light scattering signal; a sample holder coupled to the detector device and configured to position the surface of the lateral-flow chromatographic assay cassette in relation to the detector device and the illuminating light source, wherein the sample holder includes a stage configured to position the surface relative to an angle of illumination from the illuminating light source and an angle of detection to the detector device so as to optimize the elastic light scattering signal; and further comprising a computer readable program stored in a computer readable format and electronically coupled to the detector device, wherein the computer readable program is configured to convert the elastic light scattering signal to a numerical value related to the amount of at least one analyte present in the sample.
