At 633 nm wavelength, the DSPP tip generated roughly six times the electric field strength of a comparable asymmetric double-slit probe. Stable nanofocusing held across a 580 to 800 nm range, with the ...

Optical super-resolution resolves 137 nm features, matching SEM performance and exceeding a standard 100x objective.

Researchers have developed a new measurement and imaging approach that can resolve nanostructures smaller than the diffraction limit of light. After light interacts with a sample, the new technique ...

Researchers from the University of Science and Technology of China (USTC) led by Prof. ZHANG Douguo have unveiled a planar optical device that significantly enhances the capabilities of dark-field ...

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in diseases Katarina Zimmer, Knowable Magazine Key takeaways: Super-resolution ...

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 ...
