Nikon to unveil New Super Resolution Microscopes N-SIM and N-STORM

The N-SIM and N-Storm, developed with technology licensed from the University of California, San Francisco (UCSF), and from Harvard University respectively, boast to be capable of much higher resolution (N-SIM double; N-Storm 10 times more) than the conventional optical microscopes. They are announced to be introduced at the 49th Annual Meeting (December 5-9, San Diego) of American Society For Cell Biology.

Features
Super Resolution Microscope N-SIM
1. Nearly double the resolution of conventional optical microscopes
N-SIM nearly doubles the resolution of conventional optical microscopes by combining “Structured Illumination Microscopy” technology licensed from UCSF with Nikon’s renowned CFI Apo TIRF 100x oil objective lens (NA 1.49), developed using unique optical technologies and manufacturing techniques. The Structured Illumination Microscopy technology was developed by Dr. Mats G. L. Gustafsson, Dr. John W. Sedat and Dr. David A. Agard of UCSF. Dr. Agard is currently a Howard Hughes Medical Institute (HHMI) investigator at UCSF, and Dr. Gustafsson is a group leader at HHMI’s Janelia Farm Research Campus.
2. Time resolution of 0.6 sec/frame, the fastest in the industry
N-SIM provides the fastest imaging capability in the industry, with a time resolution of 0.6 sec/frame, effective for live-cell imaging.
3. New TIRF-SIM and 3D-SIM imaging technique
The newly developed TIRF-SIM illumination technique enables Total Internal Reflection Fluorescence (TIRF) observation with higher resolution than conventional TIRF microscopes and gives more detailed structural information near cell membrane. In addition, another new 3D-SIM illumination technique has the capability of optical sectioning of specimens, enabling the visualization of more detailed cell spatial structures.

Super Resolution Microscope N-STORM
1. An order of magnitude better resolution than conventional optical microscopes
N-STORM provides dramatically enhanced resolution that is more than 10 times greater than conventional optical microscopes, with “Stochastic Optical Reconstruction Microscopy” technology developed by Dr. Xiaowei Zhuang—Howard Hughes Medical Institute, Harvard University—and colleagues.
2. Image construction by overlaying single molecule images
STORM is new technology that reconstructs high resolution fluorescence images (2D or 3D) from localization information of fluorophores detected with high accuracy and calculated from multiple exposures. It generates much more information and takes us one step further, from structural to molecular understanding of the specimen.
3. Three-dimensional information capability
N-STORM will not only provide high-resolution 2D-image-acquisition capability, but it will also provide high-resolution fluorescence images of the same specimen in 3D with a simple optical system switchover built into the microscope.
