Tokyo, Japan - Scientists from Tokyo Metropolitan University have developed a new method for making ordered arrays of nanoholes in metallic oxide thin films using a range of transition metals. The ...

Other groups have developed sensors based on nanohole arrays in metal films. These sensors detect molecules via a phenomenon called surface plasmon resonance. Researchers shine light on the films, ...

Optical physicists in the UK and Spain have fabricated an array of nanoholes that can focus light into a spot that is smaller than the wavelength of light used. The research team, led by Nikolay ...

Although plasmonic super chiral fields have been successfully applied to detect the chiral structures of proteins, it has remained challenging to detect the structural handedness of drug molecules due ...
