According to the present invention, the method for detecting an explosive on the basis of quantum dots uses a change in fluorescence wavelength which is unlike a known detection method using the change in quantum dot fluorescence intensity, and thus is not sensitive to a change in surroundings, can carry out rapid detection, and can detect even a low concentration of explosives with high sensitivity. Therefore, the present invention is expected to be extensively commercialized. | 05-28-2015 |
