Fig. 1. This is explaining the immune chromatography method using quantum dots. As you can see in the figure, wéve constructed a lateral flow assay system (LFA) using target molecules (molecules that antibodies bind to) and label molecules (molecules marked with quantum dots). This LFA system is applied to the sample and detects the presence of the target molecule by leveraging specific interactions between the target molecule and the labeled molecule. The completed system has a fixed light source at a specific wavelength, and analysis is conducted through a measurement device that filters optical information through an optical filter on the image sensor lens.
