The fabrication and morphological characterization of these structures were previously reported. In this report, we electrically probed the presence of nanogap through current measurement. The effects of electrolytes to the capacitance profiles of these structures were systematically studied with air, water and various dilution of phosphate buffer saline. Increment in capacitance was found with the increment in electrolyte concentration. Improvement in current flow, capacitance, permittivity, and conductivity were observed with the smaller size nanogaps, suggesting their applications in low power consuming devices. Since nanogap-based dielectric biosensing devices needs to be operated with low level of current to avoid biomolecular damage, these structures should have potential applications in dielectric-based biomolecular detection using a low cost dielectric analyzer. 2014-03-21T04:02:29Z 2014-03-21T04:02:29Z 2013-02 Article Journal of Nanoelectronics and Optoelectronics, vol. 8(2), 2013, pages 156-159 1555-130X http://www.ingentaconnect.com/content/asp/jno/2013/00000008/00000002/art00002?token=004d19f05b1fc081741333c4a2f7a7a6a4d3b6b67667d663c444f6d62222c227e372530332976 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32944 en American Scientific Publishers
