Microscopy Systems for Instant Internal Reflection Fluorescence/Structured Illumination

[top] Description of Technology: Structured illumination microscopy (SIM) is a method that uses sharply patterned light and post-processing of images to enhance image resolution (in its linear form, doubling resolution). In traditional SIM, a series of images are acquired with a camera and computationally processed to improve resolution. This implementation of SIM has also been combined with total internal reflection fluorescence (TIRF), but the implementation still requires raw images relative to normal TIRF microscopy, thereby slowing acquisition 9-fold relative to conventional, diffraction-limited imaging. This TIRF/

SIM system includes a radial aperture block positioned at a plane conjugate to the back focal plane of the objective lens, thus allowing only high-angle marginal annular light beams from a laser source to excite the sample. The radial aperture block can be replaced with a digital micromirror device for varying the evanescent wave to allow nanometric localization of features in the axial direction. A spatial light modulator (SLM) can be used to alter the phase of the excitation to optimally induce evanescent, patterned excitation at the sample. Various embodiments of the TIRF/SIM system allows for high-speed, super-resolution microscopy at very high signal-to-noise (SNR) ratios for biological applications within ~200 nm ( e.g., the evanescent wave decay length) distance of a coverslip surface.

Potential Commercial Applications: • High speed microscopy.

Competitive Advantages: • Low cost of manufacture.

Development Stage: • Prototype.
