Nanosecond-order long–short fluorescence lifetime switchable encryption with enlarged coding capacity

Nanophotonics, 2021
The turn-off fluorescent photoswitches for information encryption are constantly being developed. However, there are no reports about time-switchable (fluorescence lifetime-switchable) encryption to overcome the limitations of tunable encoding numbers in

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

Photonics, 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).

Advanced Data Analysis for Fluorescence-Lifetime Single-Molecule Localization Microscopy

Frontiers in Bioinformatics, 2021
Fluorescence-lifetime single molecule localization microscopy (FL-SMLM) adds the lifetime dimension to the spatial super-resolution provided by SMLM. Independent of intensity and spectrum, this lifetime information can be used, for example, to quantify ...

A Review of New High-Throughput Methods Designed for Fluorescence Lifetime Sensing From Cells and Tissues

Frontiers in Physics, 2021
Though much of the interest in fluorescence in the past has been on measuring spectral qualities such as wavelength and intensity, there are two other highly useful intrinsic properties of fluorescence: lifetime (or decay) and anisotropy (or polarization)

Fluorescence lifetime imaging endoscopy [PDF]

SPIE Proceedings, 2011
We present two FLIM endoscopes for clinical imaging and in vivo cell biology. For subcellular confocal imaging we demonstrated the first confocal FLIM endomicroscope, implementing TCSPC with a Cellvizio®GI, which we have now developed as a self-contained wheeled instrument (1.0 × 0.7 m) incorporating a tunable excitation laser and acquiring images ...

Fluorescence Lifetime Imaging and Spectroscopic Co-Validation for Protoporphyrin IX-Guided Tumor Visualization in Neurosurgery

Frontiers in Oncology, 2021
Maximal safe resection is a key strategy for improving patient prognosis in the management of brain tumors. Intraoperative fluorescence guidance has emerged as a standard in the surgery of high-grade gliomas.

In vivo label-free mapping of the effect of a photosystem II inhibiting herbicide in plants using chlorophyll fluorescence lifetime

Plant Methods, 2017
Background In order to better understand and improve the mode of action of agrochemicals, it is useful to be able to visualize their uptake and distribution in vivo, non-invasively and, ideally, in the field.

ATP changes the fluorescence lifetime of cyan fluorescent protein via an interaction with His148. [PDF]

PLoS ONE, 2010
Recently, we described that ATP induces changes in YFP/CFP fluorescence intensities of Fluorescence Resonance Energy Transfer (FRET) sensors based on CFP-YFP.
