The present invention relates to a method for detecting target substance using reflectance-based colormetric analysis. In particular, according to the method for detecting target substance using reflectance-based colormetric analysis, a target substance is detected by using a target-specific aptamer, goldnano particles and salt. The goldnano particles and salt form a complex with the aptamer. The method for detecting target substance using reflectance-based colormetric analysis can use the nanogold particles having a higher density than a density of other nanogold particles used by the existing UV/VIS spectrophotometer. Therefore, very small amounts of the target substance can be detected; the volume of the sample used is small; a sample can be applied to a real-time measurement and a microchannel because the sample can be analyzed by various platforms. |
