scattering (SERS) substrates involving laser ablation and chemical routes for the trace-level …

We report an easy-to-implement device for surface-enhanced Raman scattering (SERS)-
based detection of various analytes dissolved in water droplets at trace concentrations. The …

Interaction of complex-shaped light fields with specially designed plasmonic nanostructures
gives rise to various intriguing optical phenomena like nanofocusing of surface waves …

Laser-assisted nanostructuring of silicon interfaces provides a unique procedure for leading-
edge technologies. We report on a new embossing technique with tightly focused Gaussian …

Here, we report on formation of nanoprotrusions on the surface of a bulk crystalline silicon
wafer under femtosecond-laser ablation with a donut-shaped laser beam. By breaking …

In this work, microscale holes and intermediate self-organized structures were obtained on
the surface of a thin 50-nm silver film in air and under a water layer using single tightly …

In the last few decades, micro-texturing has become a widely studied technique to modify
the frictional behavior between surfaces in both dry and lubricated regimes. Among all the …

In this study, the influence of femtosecond double-pulses in inducing bulge structures on thin
gold films were experimentally examined. The experimental results indicate that the …

We report the possibility of a time-resolved bacterial live/dead dynamics observation with the
use of plasmonic nanospikes. Sharp nanospikes, fabricated on a 500-nm thick gold film by …
