Abstract: A gas sensor includes a substrate, a pair of electrodes formed on the substrate, having a nanogap formed therebetween, and facing each other, and metal nanoparticles present in the nanogap, wherein a ligand organic single-molecule having a gas-bonding functional group and a ligand organic single-molecule having a substrate-bonding functional group are disposed on the surface of the metal nanoparticles, and wherein an organic single-molecule having a substrate-functional group bonding to the substrate-bonding functional group of the ligand organic single-molecule having a substrate-bonding functional group disposed on the surface of the metal nanoparticles is immobilized to the substrate, a method for manufacturing the gas sensor, and a use thereof.
