New fluorescence microscopy system enables super-resolution imaging of single molecules across a 40x wider field of view.
Researchers at the University of Central Florida have invented a fluorescence microscope that provides better real-time imaging of single molecules than conventional fluorescence technologies such as HILO (highly inclined and laminated optical sheet) microscopy. By enabling a much higher signal-to-background-ratio and a wider field-of-view (FOV), the UCF Highly Inclined Swept Tile (HIST) microscope delivers thinner illumination with greater than 40x FOV; thus providing clearer visualization of single molecules across a >130µm x 130µm FOV. With such capabilities, the innovation can benefit applications such as super-resolution imaging, single-molecule tracking, and smFISH-based high-throughput gene expression profiling.
The UCF HIST technology is a fluorescence microscope that uses a highly inclined tile beam to scan over a biological sample object. The system spatially filters fluorescence emission from the sample through a programmable confocal slit into an sCMOS camera supporting a rolling shutter mode. The tile beam is synchronously swept with the readout of the camera to facilitate the rejection of background. The system provides for decoupling of the total imaging area from the beam thickness, which solely depends on the width of the tile beam, enabling a thinner illumination (high sectioning capability) and larger FOV for video-rate, live-cell imaging. The technology can be easily implemented onto a standard inverted microscope.
The research team is looking for partners to develop the technology further for commercialization.
