Super-resolution Fluorescence Microscopy

14.9K
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:

  • Nanotechnology
  • Optics
  • Materials Science

Background:

  • 3D remote control of multifunctional fluorescent up-converting nanoparticles (UCNPs) is crucial for advanced applications.
  • Current limitations stem from weak optical forces (tens of fN) on small UCNPs (around 10 nm).

Purpose of the Study:

  • To overcome the limitation of weak optical forces on UCNPs.
  • To enhance the optical forces acting on UCNPs for improved 3D remote control.

Main Methods:

  • Controlled modification of the UCNP/medium interface.
  • Substitution of cationic species at the nanoparticle surface with higher mobility species.

Main Results:

  • Optical forces acting on UCNPs were enhanced by over one order of magnitude.
  • Achieved UCNP trapping constants comparable to those of metallic nanoparticles.

Conclusions:

  • Surface modification significantly boosts optical forces on UCNPs.
  • Enhanced optical forces open new possibilities for nanoscale applications requiring precise control.
