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...

    • Cell Biology
    • Microscopy

    Background:

    • Live-cell fluorescence microscopy is crucial for observing cellular dynamics.
    • Current systems often lack portability and adaptability for in situ imaging.
    • Miniaturization offers a solution for developing portable cell imaging systems.

    Purpose of the Study:

    • To provide a protocol for constructing and operating a miniaturized modular-array fluorescence microscopy (MAM) system.
    • To enable in situ, long-term live-cell imaging within incubators.
    • To guide scientists in building compact, portable fluorescence imaging devices.

    Main Methods:

    • Construction of a miniaturized modular-array fluorescence microscopy (MAM) system (15cm x 15cm x 3cm).
    • Demonstration of system stability using fluorescent targets and live HeLa cells.
    • In situ imaging within an incubator with subcellular lateral resolution (~3µm).

    Main Results:

    • The MAM system achieved stable, long-term imaging for 12 hours.
    • The system enabled in situ cell imaging without external support or post-processing.
    • Subcellular lateral resolution of approximately 3µm was achieved.
