  • Metal chalcogenide quantum dots for the detection of nitroaromatic chemicals
    Patent number: 10119953
    Abstract: The synthesis of AgInS2 based quantum dots and their use as fluorometric probes for the selective detection of nitroaromatic explosive chemicals, without the use of ligands specific to nitroaromatic explosive chemicals. These quantum dots allow the detection of nitroaromatic explosive molecules by eye. The present invention also represents a simple patterning method for quantum dots on substrates, including low cost filter paper. The ease of fabrication, use of less toxic materials, and the selectivity to nitroaromatic explosive chemicals results in a practical solution to the development of a portable fluorescent probe based on quantum dots for the detection of nitroaromatic explosive chemicals.
