Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

In 1873, Ernst Abbe proposed the famous diffraction limit theory, stating that the resolution of an optical system is limited by the light wavelength ...

Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...

For over a century, light has both helped and limited our view of the tiny world. Microscopes use light to magnify cells, microbes, and nanomaterials—but light also behaves like a wave, and waves ...

A technical paper titled “Scalable nanopatterning of organic light-emitting diodes beyond the diffraction limit” was published by researchers at ETH Zurich, University of Alberta, Indian Institute of ...
