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 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 ...

(a) Working principle of metasurface displacement measurement can be understood as the detection of the power of different modes of the converted light. The incident irradiated on the metasurface and ...

What is Single-Molecule Localization Microscopy? Single-molecule localization microscopy (SMLM) is a super-resolution imaging technique that enables the visualization of biological structures and ...

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 ...
