Noble metal nanoslit structure has attracted an increasing interest in nanoscale photonic devices, and bio applications. However, methods typically used for fabricating nano-sized slit, such as, e-beam direct etching, template-assisted photolithography, and nano-imprint lithography, have low yield and are limited to sub-nano sized slit. In this work, we observed that slit width of Au metal is g...

Orthopaedic and dental implants have become a staple of the medical industry and with an ageing population and growing culture for active lifestyles, this trend is forecast to continue. In accordance with the increased demand for implants, failure rates, particularly those caused by bacterial infection, need to be reduced. The past two decades have led to developments in antibiotics and antibac...

In Nature, the intrinsic cooperation between organism’s parts is capital. Most living systems are composed of organs, functional units specialized for specific actions. In our last research, we developed an evolutionary model able to generate artificial organs. This paper deals with the assembly of organs. We show, through experimentation, the development of an artificial organism composed of f...

To amplify the difference in localized surface plasmon resonance (LSPR) spectra of gold nano-islands due to intermolecular binding events, gold nanoparticles were used. LSPR-based optical biosensors consisting of gold nano-islands were readily made on glass substrates using evaporation and heat treatment. Streptavidin (STA) and biotinylated bovine serum albumin (Bio-BSA) were chosen as the mode...
