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 ...

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, ...
