Gold nano-ripple structure with potential for bio molecular sensing applications

Plasmonic Nanostructures for Nano-Scale Bio-Sensing

The optical properties of various nanostructures have been widely adopted for biological detection, from DNA sequencing to nano-scale single molecule biological function measurements. In particular, by employing localized surface plasmon resonance (LSPR), we can expect distinguished sensing performance with high sensitivity and resolution. This indicates that nano-scale detections can be realiz...

Nano SAW Devices For Sensing Applications

Molecular Dynamics Simulations of Nano-Bio Materials

radically different computing concepts that leverage the physics of biological materials. For example, selforganization, self-repair, and self-reproduction are commonly found in biological systems but are difficult to achieve with conventional computing systems. New computing paradigms, such as cellular automata, neural networks, and evolutionary computing, may provide clues to utilize the comp...

A nanoporous gold membrane for sensing applications.

Design and fabrication of three-dimensionally structured, gold membranes containing hexagonally close-packed microcavities with nanopores in the base, are described. Our aim is to create a nanoporous structure with localized enhancement of the fluorescence or Raman scattering at, and in the nanopore when excited with light of approximately 600 nm, with a view to provide sensitive detection of b...

Gold/diamond nanohybrids for quantum sensing applications

Recent advances in quantum technology have demonstrated the potential use of negatively charged nitrogen-vacancy (NV) centers in diamond for temperature and magnetic sensing at sub-cellular levels. Fluorescent nanodiamonds (FNDs) containing high-density ensembles of NV centers are appealing for such applications because they are inherently biocompatible and non-toxic. Here, we show that FNDs co...
