Homologous Recombination under the Single-Molecule Fluorescence Microscope [PDF]

open access: yes, 2019
Homologous recombination (HR) is a complex biological process and is central to meiosis and for repair of DNA double-strand breaks. Although the HR process has been the subject of intensive study for more than three decades, the complex protein–protein ...

Polarization effects on fluorescence emission of zebrafish neurons using light-sheet microscopy [PDF]

open access: yesarXiv, 2022
Light-sheet fluorescence microscopy (LSFM) makes use of a thin plane of light to optically section and image transparent tissues or organisms {\it{in vivo}}, which has the advantages of fast imaging speed and low phototoxicity. In this paper, we have employed light-sheet microscopy to investigate the polarization effects on fluorescence emission of ...

Quantitative Imaging of Protein-Protein Interactions by Multiphoton Fluorescence Lifetime Imaging Microscopy using a Streak camera [PDF]

open access: yesJournal of Biomedical Optics Vo.8, 362 (July 2003), 2003
Fluorescence Lifetime Imaging Microscopy (FLIM) using multiphoton excitation techniques is now finding an important place in quantitative imaging of protein-protein interactions and intracellular physiology. We review here the recent developments in multiphoton FLIM methods and also present a description of a novel multiphoton FLIM system using a ...

miR-203 drives breast cancer cell differentiation

open access: yesBreast Cancer Research, 2023
A hallmark of many malignant tumors is dedifferentiated (immature) cells bearing slight or no resemblance to the normal cells from which the cancer originated.

Epi-Fluorescence Microscopy [PDF]

open access: yes, 2012
Epi-fluorescence microscopy is available in most life sciences research laboratories, and when optimized can be a central laboratory tool. In this chapter, the epi-fluorescence light path is introduced and the various components are discussed in detail.

In vitro reconstitution of microtubule dynamics and severing imaged by label-free interference reflection microscopy [PDF]

open access: yesarXiv, 2021
The dynamic architecture of the microtubule cytoskeleton is crucial for cell division, motility and morphogenesis. The dynamic properties of microtubules - growth, shrinkage, nucleation and severing - are regulated by an arsenal of microtubule-associated proteins (MAPs).

3D Computational Cannula Fluorescence Microscopy enabled by Artificial Neural Networks [PDF]

open access: yes, 2020
Computational Cannula Microscopy (CCM) is a high-resolution widefield fluorescence imaging approach deep inside tissue, which is minimally invasive. Rather than using conventional lenses, a surgical cannula acts as a lightpipe for both excitation and fluorescence emission, where computational methods are used for image visualization.

Blind fluorescence structured illumination microscopy: A new reconstruction strategy [PDF]

open access: yes, 2016
In this communication, a fast reconstruction algorithm is proposed for fluorescence \textit{blind} structured illumination microscopy (SIM) under the sample positivity constraint.

Super-resolution fluorescence microscopy by stepwise optical saturation [PDF]

open access: yesBiomed. Opt. Express 9, 1613-1629 (2018), 2018
Super-resolution fluorescence microscopy is an important tool in biomedical research for its ability to discern features smaller than the diffraction limit. However, due to its difficult implementation and high cost, the universal application of super-resolution microscopy is not feasible.

Efficient non-degenerate two-photon excitation for fluorescence microscopy [PDF]

open access: yes, 2019
Non-degenerate two-photon excitation (ND-TPE) has been explored in two-photon excitation microscopy. However, a systematic study of the efficiency of ND-TPE to guide the selection of fluorophore excitation wavelengths is missing. We measured the relative
