A simple method for filling nanogap electrodes with polymer.
We have developed a relatively simple and cost-effective procedure capable to fill nanogap electrodes with a polymer. The polymer deposit into nanogap electrodes was achieved via pinning the solution droplet edge over the nanogap. During solvent evaporation from the droplet, a ringlike deposit forms along its edge. Pinning of the solution droplet was performed by a needle connected to a micromanipulator. After drying, the surplus of the nitrocellulose deposit was removed by the motion of another solvent droplet driven across the nanogap electrodes.
