Interactive Database for 2-Photon-Based Oxygen Phosphorescence Lifetime Imaging Data
Biophotonics Congress 2021, 2021We present a graphical user interface-based database software for visualization, analysis, and export of experimental data of two-photon-based phosphorescence lifetime imaging of oxygen concentrations in the somatosensory cortex of awake mice.

Oxygen Assessment in Tumors In Vivo Using Phosphorescence Lifetime Imaging Microscopy
Methods in Molecular BiologyThe oxygen level in a tumor is a crucial factor for its development and response to therapies. Phosphorescence lifetime imaging (PLIM) with the use of phosphorescent oxygen probes is a highly sensitive, noninvasive optical technique for the assessment of molecular oxygen in living cells and tissues.

Journal of the American Chemical Society
Methionine sulfoxide reductases (Msrs) are essential for preserving redox homeostasis in the nervous system, with dysregulation implicated in Alzheimer's disease (AD). Conventional fluorescence-based assays for Msrs activity sensing are hampered by background interference, limited sensitivity, and inadequate quantification. This work introduces a novel

Phosphorescence lifetime imaging in turbid media
2021In this dissertation we explore the use of highly scattered photons in an analog of conventional emission tomography. Through this technique we quantitatively reconstruct images of the spatial distribution of oxygen in turbid media. We begin with the mathematical description of diffusive light propagation in highly scattering systems and solve the ...

Singlet Oxygen Phosphorescence Lifetime Imaging Based on a Fluorescence Lifetime Imaging Microscope
The Journal of Physical Chemistry A, 2015The feasibility of singlet oxygen phosphorescence (SOP) lifetime imaging microscope was studied on a modified fluorescence lifetime imaging microscope (FLIM). SOP results from the infrared radiative transition of O2(a(1)Δg → X(3)Σg(-)) and O2(a(1)Δg) was produced in a C60 powder sample via photosensitization process. To capture the very weak SOP signal,

Combined fluorescence and phosphorescence lifetime imaging
Applied Physics Letters, 2016We present a lifetime imaging technique that simultaneously records the fluorescence and phosphorescence lifetime images in confocal laser scanning systems. It is based on modulating a high-frequency pulsed laser synchronously with the pixel clock of the scanner, and recording the fluorescence and phosphorescence signals by multidimensional time ...

Simultaneous fluorescence and phosphorescence lifetime imaging
SPIE Proceedings, 2011We present a lifetime imaging technique that simultaneously records fluorescence and phosphorescence lifetime images in laser scanning systems. It is based on modulating a high-frequency pulsed laser by a signal synchronous with the pixel clock of the scanner, and recording the fluorescence and phosphorescence signals by multi-dimensional TCSPC ...
