Abstract:
1. A nanogap sensor for detecting variations of an analysis object in electrical characteristics, comprising: a substrate having V-shaped section thereon, the V-shaped section including a top width at a top portion of the substrate and a bottom width at a bottom portion of the substrate in such a configuration that the bottom width has a nano-scaled gap size of several nanometers to several hundreds of nanometers; an oxide layer on a surface of the substrate including both sidewalls of the V-shaped section opposite to each other, thereby decreasing the width of the V-shaped section; and a pair of electrodes on the oxide layer extending to both of the sidewalls of the V-shaped section to a top surface of the substrate, respectively, the analysis object being attached to each of the electrodes close to the bottom width of the V-shaped section, respectively.
