Numerical Simulation of the Photobleaching Process in Laser-Induced Fluorescence Photobleaching Anemometer [PDF]

open access: yesMicromachines, 2021
At present, a novel flow diagnostic technique for micro/nanofluidics velocity measurement—laser-induced fluorescence photobleaching anemometer (LIFPA)—has been developed and successfully applied in broad areas, e.g., electrokinetic turbulence in ...

The Impact of Photobleaching on Microarray Analysis [PDF]

open access: yesBiology, 2015
DNA-Microarrays have become a potent technology for high-throughput analysis of genetic regulation. However, the wide dynamic range of signal intensities of fluorophore-based microarrays exceeds the dynamic range of a single array scan by far, thus ...

Nonexponential statistics of fluorescence photobleaching [PDF]

open access: yesThe Journal of Chemical Physics, 2004
In this paper, I consider theoretical models of the decay via photobleaching of a sample of surface-immobilized fluorescent molecules excited by a spatially varying laser intensity profile. I show that, with mild restrictions on the photobleaching mechanism, the fluorescence decay measured in a nonuniform excitation profile is always nonexponential ...

Multispectral imaging and autofluorescence photobleaching combined in a multi-head neural network for skin cancer classification [PDF]

open access: yesFrontiers in Medicine
IntroductionThe classification of hyperspectral images for skin cancer presents a significant challenge due to high data dimensionality and subtle differences between melanoma and non-melanoma tissues. This study investigates the efficacy of multi-target,

Photobleaching in Two-Photon Excitation Microscopy [PDF]

open access: yesBiophysical Journal, 2000
The intensity-squared dependence of two-photon excitation in laser scanning microscopy restricts excitation to the focal plane and leads to decreased photobleaching in thick samples. However, the high photon flux used in these experiments can potentially lead to higher-order photon interactions within the focal volume.

Photobleaching Photoacid Generator.

open access: yesJournal of Photopolymer Science and Technology, 2001
A cyclopropyl group was introduced into the photoacid generator in order to give the photobleaching property at 193nm. Cyclopropyldiphenylsulfonium trifluoromethanesulfonate (CpDP-Tf) was synthesized for this photobleaching effect. This compound is stable up to 165°C. The absorbance of CpDP-Tf at 193nm decreases upon exposure.

Effects of second order photobleaching on recovered diffusion parameters from fluorescence photobleaching recovery

open access: yesBiophysical Journal, 1991
In the original theoretical development of fluorescence photobleaching recovery with circular or Gaussian laser intensity profiles (Axelrod et al., 1976, Biophys. J.) the bleaching process is assumed to obey first order kinetics in the fluorescent probe.

Dynamic Mode Decomposition of Fluorescence Loss in Photobleaching Microscopy Data for Model-Free Analysis of Protein Transport and Aggregation in Living Cells

open access: yesSensors, 2022
The phase separation and aggregation of proteins are hallmarks of many neurodegenerative diseases. These processes can be studied in living cells using fluorescent protein constructs and quantitative live-cell imaging techniques, such as fluorescence ...

Spectroscopic study of methylene blue photophysical properties in biological media

open access: yesBiomedical Photonics, 2023
A spectroscopic study of the photophysical properties of methylene blue (MB) in aqueous solutions was carried out. Absorption and fluorescence spectra as well as fluorescence lifetime were recorded. The concentration dependence of the intensity and shape
