Nanopillar array structures for enhancing biosensing performance

Fabrication of metallic nanopillar array structures and their application as electrodes in electrochemical-based biosensors are discussed in this report. Vertically standing nanopillar array structures were fabricated using an electrodeposition technique and their electrochemical characteristics were evaluated. For possible use in biosensing applications, these standing nanopillars should have ...

Silicon nanopillar arrays with SiO2 overlayer for biosensing application

We present the fabrication of silicon dioxide (SiO2) coated silicon nanopillar array structures and demonstrate their application as sensitive optical biosensors. Colloidal lithography, plasma dry etching and deposition processes are used to fabricate SiO2 coated Si nanopillar arrays with two different diameters and periods. Proof of concept bio recognition experiments are carried out with the ...

Enhanced Humidity Sensitivity with Silicon Nanopillar Array by UV Light

The sensitivity of silicon nanopillar array for relative humidity (RH) with UV illumination was investigated in this work. The silicon nanopillar array was prepared by nanosphere lithography. Electrical measurements were performed on its sensing performance with and without UV irradiation. It was found that UV light improved the humidity sensitivity with different UV light wavelengths and power...

Hexagonal organic nanopillar array from the melamine-cyanuric acid complex.

We report a well-defined, organic, hexagonal nanopillar array on a gold surface. The array was prepared from a cyanuric acid-melamine complex by means of sequential mixing on the gold surface. These nanopillars had uniform diameters of 200-400 nm and were 1 microm in length. They were well faceted with hexagonal cross sections. The nanopillars had a crystalline structure, and the pillars exhibi...
