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 ...

(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 ...

Processes in the human body are shaped by the interaction of various biomolecules, such as proteins and DNA. These processes take place in a range of often just a few nanometers. They can therefore no ...
