Discovery of huge Raman scattering at atomic point contact

Nanofabrication of electronic devices has reached a single nanometer scale (10-9 m). The rapid advancement of nanoscience and nanotechnology now requires atomic-scale optical spectroscopy in order to characterize atomistic ...

Nanomotors controlled with laser light

Researchers from the Institute of Industrial Science, the University of Tokyo (UTokyo-IIS) have designed novel linear nanomotors that can be moved in controlled directions using light. This work opens the way for new microfluidics, ...

White nanolight source for optical nanoimaging

Nanolight sources based on resonant excitons of plasmons near a sharp metallic nanostructure have attracted great interest in optical nanoimaging. However, the resonant phenomenon only works for one type of wavelength that ...

Smallest cavity for light realized by graphene plasmons

Miniaturization has enabled technology like smartphones, health watches, medical probes and nano-satellites, all unthinkable a couple decades ago. Just imagine that in the course of 60 years, the transistor has shrunk from ...

New COVID-19 test quickly and accurately detects viral DNA

Millions of people have been tested for the novel coronavirus, most using a kit that relies on the polymerase chain reaction (PCR). This sensitive method amplifies SARS-CoV-2 RNA from patient swabs so that tiny amounts of ...
