Abstract
A method and a device for detecting the presence of a predetermined substance, in which a quantum dot is produced on a substrate. The quantum dot emits a radiation at a predetermined wavelength, and is covered with a surface layer to which the predetermined substance attaches. A deviation of the value of a parameter related to the radiation is produced when the predetermined substance attaches to the surface layer. This deviation can be detected to thereby sense the presence of the predetermined substance.
Claims11
A device for detecting a presence of a predetermined substance in a liquid, comprising:
- a substrate;
- an epitaxial quantum dot directly on a face of the substrate, the quantum dot emitting a radiation at a predetermined wavelength;
- and
- passivating layers including a cap covering the quantum dot, structured to attach the predetermined substance and produce a deviation of a value of a parameter related to the radiation when the predetermined substance attaches to a portion of the passivating layers.
