Viral particle imaging by super-resolution fluorescence microscopy

open access: yesChemical Physics Impact, 2021
Fluorescence microscopy provides a facile imaging methodology and potentials for imaging viruses in vivo. However, it is limited by the diffraction limit of light microscopy which is above the size of the virus particles.

Two-step excitation of fluorescent proteins with real intermediary states [PDF]

open access: yesarXiv
We demonstrate sequential two-photon fluorescence microscopy using forbidden state transitions. Nonlinear red excitation leads to green fluorescence in live cells expressing eYFP, maintaining optical sectioning and allowing deep tissue imaging with simple optical systems.

Optical sectioning in fluorescence microscopy

open access: yesJournal of Microscopy, 2010
We review the origins of optical sectioning in fluorescence microscopy in terms of the structure of the illumination used to generate the fluorescence within the specimen. We note that the conventional microscope using essentially uniform illumination does not exhibit optical sectioning whereas the confocal microscope using point (many spatial ...
