Super-resolution Fluorescence Microscopy

7.1K
Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been...

    Area of Science:

    • Microscopy
    • Biotechnology
    • Image Analysis

    Background:

    • Single molecule localization microscopy (SMLM) shows promise for high-throughput screening.
    • Optimizing imaging throughput without compromising image quality, particularly resolution homogeneity, remains a challenge for SMLM in heterogeneous samples.

    Purpose of the Study:

    • To develop a real-time image resolution measurement method for SMLM.
    • To address the limitation of maintaining homogeneous resolution during high-throughput imaging of multiple fields of view (FOVs).

    Main Methods:

    • Introduced a real-time image resolution measurement method for SMLM.
    • Employed a heuristic framework for overall image resolution, considering localization precision and density.
    • Utilized the spatial Poisson process to model molecule activation and determine real-time localization density, avoiding post-acquisition estimation.

    Main Results:

    • Validated the method for real-time resolution measurement in SMLM.
    • Demonstrated effective guarantee of homogeneous image resolution across multiple FOVs.
    • Achieved optimized imaging throughput without sacrificing image quality.

    Conclusions:

    • The developed real-time method enables efficient and high-quality SMLM imaging.
    • This approach is effective for heterogeneous samples, ensuring consistent resolution and optimized throughput.
    • Facilitates broader applications of SMLM in high-throughput screening.
