Metal nanoparticles potentially able to immobilize the enzymes according to unique properties including large surface-to-volume ratio, high surface reaction activity, high catalytic efficiency, and strong adsorption ability. A novel and highly sensitive amperometric glucose biosensor was obtained by using ...

Inside Front Cover In article number 2100277, Lee, Jung, and co-workers develop an ultrasensitive molecule detection platform for surface-enhanced infrared absorption spectroscopy. Based on using a metamaterial absorber with 10 nm-thick vertical nanogap processed via nanoimprint lithography isotropic dry-etching, record-high reflection difference signal 1-octacanethiol monolayer is achieved.

the transformation of biochemical information into a physical or chemical signal is the basic idea behind a biosensor. the efficient detection of charged biomolecules by biosensor with appropriate device has caught tremendous research interest in the present decade. the present work is related to the simulation study of the performance of a functionalized surface of a biologically sensitive fie...

Coplanar radio frequency Schottky diodes based on solution-processed C60 and ZnO semiconductors are fabricated via adhesion-lithography. The development of a unique asymmetric nanogap electrode architecture results in devices with a high current rectification ratio (10(3) -10(6) ), low operating voltage (<3 V), and cut-off frequencies of >400 MHz. Device fabrication is scalable and can be perfo...

The present study investigates the angular response and sensitivity of a surface plasmon resonance biosensor with metamaterial, by taking the advantage of the remarkable property of metamaterials. The proposed biosensor numerically shows that silver with a metamaterial layer enhances the sensitivity. The thickness of metamaterial and silver layer has been optimized. On comparing these results w...

The response of a peroxidase-based optical biosensor was modelled digitally.A mathematical model of the optical biosensor is based on a system of non-linear reaction-diffusion equations. The modelling biosensor comprises two compartments, an enzyme layerand an outer diffusion layer. The digital simulation was carried out using finite differencetechnique. The influence of the substrate concentra...

Abstract Plasmonic nanostructures have considerable applicability in light–matter interactions owing to their capacity for strong field confinement and enhancement. Nanogap structures allow us tailor electric distributions at the nanoscale, bridging differences size shape of atomic light structures. In this study, we demonstrated that a plasmonic tetramer structure can squeeze structured into n...

The consistent motivation to observe molecular electronics and quantum effects drives the need for tunable robust fabrication of nanogap devices. Electron beam lithography (EBL) offers high fidelity construct arrayed nanogaps, methods have been developed achieve sub-10 nm channel widths. However, many these approaches involve multiple steps or specialized techniques that limit throughput univer...
