Luminescent probes for luminescence lifetime sensing and imaging in live cells: a narrative review

open access: yesJournal of Bio-X Research, 2020
. Luminescence (mostly fluorescence and phosphorescence) probes are a powerful tool widely used in the life sciences research. They can be used, for example, in the quantitative analysis of physiological parameters, visualization of different cell ...

Label-Free Macroscopic Fluorescence Lifetime Imaging of Brain Tumors

open access: yesFrontiers in Oncology, 2021
Advanced stage glioma is the most aggressive form of malignant brain tumors with a short survival time. Real-time pathology assisted, or image guided surgical procedures that eliminate tumors promise to improve the clinical outcome and prolong the lives ...

Hadamard-transform fluorescence-lifetime imaging

open access: yesOptics Express, 2016
We discuss a Hadamard-transform-based fluorescence-lifetime-imaging (HT-FLI) technique for fluorescence-lifetime-imaging microscopy (FLIM). The HT-FLI uses a Fourier-transform phase-modulation fluorometer (FT-PMF) for fluorescence-lifetime measurements, where the modulation frequency of the excitation light is swept linearly in frequency from zero to a

An automated multiwell plate reading flim microscope for live cell autofluorescence lifetime assays [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2014
Fluorescence lifetime imaging (FLIM) is increasingly used to read out cellular autofluorescence originating from the coenzyme NADH in the context of investigating cell metabolic state.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Fluorescence lifetime DNA-PAINT for multiplexed super-resolution imaging of cells

open access: yesCommunications Biology, 2022
Oleksiievets et al. combine single-molecule localization super-resolution microscopy technique DNA-PAINT with fluorescence lifetime imaging to allow fast multi-target super-resolution imaging in one spectral region by separating two or three different ...

Molecular Probes for Fluorescence Lifetime Imaging [PDF]

open access: yesBioconjugate Chemistry, 2015
Visualization of biological processes and pathologic conditions at the cellular and tissue levels largely relies on the use of fluorescence intensity signals from fluorophores or their bioconjugates. To overcome the concentration dependency of intensity measurements, evaluate subtle molecular interactions, and determine biochemical status of ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

open access: yesFEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

PDT-Induced Variations of Radachlorin Fluorescence Lifetime in Living Cells In Vitro

open access: yesPhotonics, 2023
Variations in the fluorescence lifetimes of Radachlorin photosensitizers in HeLa and A549 cells, caused by photodynamic treatment, were studied using fluorescence lifetime imaging microscopy (FLIM).
