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 looming 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.
