Method for 3D Nonlinear Structured Illumination Super-resolution Imaging

Researchers at the University of Arizona have developed a super-resolution microscopy method that is faster, easier to use, and has less artifacts than current super-resolution methods. The result is a 3D dual-color stimulated emission depletion (STED) nonlinear structured illumination (NL-SIM) microscope. Using a combination of low coherent light and...
