Title: Use of Low-Coherence Source to Achieve 3D Super-Resolution Imaging
Invention: 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 time-gated detection, the microscope has improved lateral and axial resolution.
Background: Current super-resolution microscopy allows live 3D imaging of cellular processes at tens of nanometer resolution, but lacks super-resolution in the axial dimension. The systems are also complex and carry a high risk of artifacts. There is a need in the art for greater axial resolution, and a system that is easier to use with high quality results.
* Commercial (hospital/clinic analysis of biological samples)
* General research tool for studying processes and mechanisms in cells
* Improved resolution in axial and lateral dimensions
* Images sample structures as dim as single molecule and as bright as stained and fixed cells under identical experiment parameters
* High speed reduces artifacts
