A multi-layer nanogap array composed of three linearly aligned gold nanogaps is fabricated for a surface-enhanced Raman spectroscopy (SERS) substrate. The overall process for the proposed structure is simple and reliable with the use of a photolithography-free fabrication process, which includes only deposition and etching. Chemical vapor deposition (CVD) is employed to form a uniform and highl...

This paper presents a dual gate dielectric modulated FET (DGDMFET) biosensor with enhanced sensitivity for covid detection. In earlier literature, the biosensors are operated using surface interaction virus biomolecules that reflected through channel or gate. The downside of these types sensors has limited sensitivity. this paper, we have considered change in constant due to proteins results si...

Submitted for the MAR14 Meeting of The American Physical Society Large vacuum Rabi splitting for a semiconductor nanogap cavity MITSUHARU UEMOTO, HIROSHI AJIKI, Osaka University — A metallic nanogap utilizing surface plasmon excitation is one of the most popular designs of an optical antenna converting propagating radiation into enhanced fields at a nanoscale area (hotspot). Similarly, a nanoga...

I propose a technique for reading the base sequence of a single DNA molecule using a graphene nanogap to read the DNA's transverse conductance. Because graphene is a single atom thick, single-base resolution of the conductance is readily obtained. The nonlinear current-voltage characteristic is used to determine the base type independent of nanogap-width variations that cause the current to cha...

Highly stable, nonvolatile, high-temperature memory based on resistance switching was realized using a polycrystalline platinum (Pt) nanogap. The operating temperature of the memory can be drastically increased by the presence of a sharp-edged Pt crystal facet in the nanogap. A short distance between the facet edges maintains the nanogap shape at high temperature, and the sharp shape of the nan...

Erythropoietin (EPO), a glycoprotein hormone of ∼ 34 kDa, is an important hematopoietic growth factor, mainly produced in the kidney and controls the number of red blood cells circulating in the blood stream. Sensitive and rapid recombinant human EPO (rHuEPO) detection tools that improve on the current laborious EPO detection techniques are in high demand for both clinical and sports industry. ...

On-chip integration of plasmonics and electronics can benefit a broad range applications in biosensing, signal processing, optoelectronics. A key requirement is chip-scale manufacturing method. Here, we demonstrate split-trench resonator platform that combines high-quality-factor resonant plasmonic biosensor with radio frequency (RF) nanogap tweezers. The simultaneously serve as dielectrophoret...

Metallic structures with nanogap features have proven highly effective as building blocks for plasmonic systems, as they can provide a wide tuning range of operating frequencies and large near-field enhancements. Recent work has shown that quantum mechanical effects such as electron tunnelling and nonlocal screening become important as the gap distances approach the subnanometre length-scale. S...
