Abstract
A molecular detection apparatus according to an embodiment includes: a distributor which ionizes a target containing substances to be detected, applies voltage to ionized substances, and extracts the substances to be detected according to a time-of-flight based on the speed; a detector which detects the substance to be detected dropped from the distributor; and a discriminator which discriminates the substance to be detected. The detector includes: a plurality of detection units including field effect transistors using graphene layers; and a plurality of organic probes which are provided on the graphene layers, and at least some of which have different bond strengths with the substances to be detected. The substance to be detected is discriminated depending on a signal pattern based on intensity differences of the detection signals generated by differences in the bond strengths between the organic probes and the substances to be detected.
