Molecular detection apparatus and molecular detection method

A molecular detection apparatus, comprising:

• a collection unit including a collection port collecting a detection target gas containing a molecule to be detected, and an outlet port for the molecule to be detected;
• a detector comprising a first detection cell disposed to face the output port of the collection unit, which includes a first sensor unit including a field effect transistor having a graphene layer, and a source electrode and a drain electrode connected to the graphene layer, and a first organic probe provided in the graphene layer of the first sensor unit, the first organic probe including a dicyanovinyl structure or a coumarin structure which includes a double bond site capturing the molecule collected in the collection unit;
• and
• a discriminator configured to discriminate the molecule based on a detection signal generated from the first sensor unit by the molecule being captured by the first organic probe of the first detection cell.
