Abstract
The present invention provides a nanohybrid type nitrogen monoxide detecting sensor and a production method therefor in which the nanohybrid type nitrogen monoxide detecting sensor includes a fluorescent semiconducting quantum dot and a transition metal compound. Employing a nanohybrid structure including semiconducting quantum dot nano-particles combined with a molecule recognizer selectively forming a bonding to nitrogen monoxide, the nitrogen monoxide detecting sensor is enabled to detect an infinitesimal amount of nitrogen monoxide by bringing about photoluminescence upon detection of nitrogen monoxide.

A nanohybrid type nitrogen monoxide detecting sensor comprising:
- a fluorescent semiconducting quantum dot;
- and
- a transition metal compound, wherein the transition metal compound includes at least one transition metal selected from the group consisting of iron (Fe), cobalt (Co), copper (Cu), ruthenium (Ru) and rhodium (Rh), and a ligand selected from the group consisting of carboxyl, amine, porphyrin and thiol;
- wherein the fluorescent semiconducting quantum dot and the transition metal compound are bonded together to form the nanohybrid type nitrogen monoxide detecting sensor;
- wherein the nitrogen monoxide detecting sensor releases the fluorescent semiconducting quantum dot in presence of nitrogen monoxide, wherein the nitrogen monoxide detecting sensor signals detection of nitrogen monoxide by fluorescence of the fluorescent semiconducting quantum dot released from the nitrogen monoxide detecting sensor.
A method for producing a nanohybrid type nitrogen monoxide detecting sensor, comprising:
- decomposing an organometallic compound precursor through pyrolysis to synthesize a quantum dot solution having a core-shell structure;
- surface-modifying the quantum dot solution to synthesize an aqueous quantum dot;
