Noninvasive imaging of focal atherosclerotic lesions using fluorescence molecular tomography [PDF]
, 2014 Insights into the etiology of stroke and myocardial infarction suggest that rupture of unstable atherosclerotic plaque is the precipitating event. Clinicians lack tools to detect lesion instability early enough to intervene, and are often left to manage ...

Timing and Operating Mode Design for Time-Gated Fluorescence Lifetime Imaging Microscopy
The Scientific World Journal, 2013 Steady-state fluorence imaging and time-resolved fluorescence imaging are two important areas in fluorescence imaging research. Fluorescence lifetime imaging is an absolute measurement method which is independent of excitation laser intensity ...

Ultrafast photochemistry produces superbright short-wave infrared dots for low-dose in vivo imaging
Nature Communications, 2020 Deep tissue imaging has been limited by the low brightness of probes emitting in the second near-infrared window. Here, the authors use femtosecond laser irradiation to grow a protective shell on Ag2S nanoparticles, achieving 80-fold quantum yield ...

Spatial and temporal pulse shaping for lateral and depth resolved two-photon excited fluorescence contrast [PDF]
, 2019 We report combined temporal and spatial laser pulse shaping to perform lateral and depth dependent two-photon excited fluorescence of dyes. For generating the specific spatially and temporally phase tailored pulses a temporal pulse shaper and a ...

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 ...

Endosomal H2O2 Molecules Act as Signaling Mediators in Akt/PKB Activation
AntioxidantsReceptor-mediated endocytosis (RME) is a commonly recognized receptor internalization process of receptor degradation or recycling. However, recent studies have supported that RME is closely related to signal propagation and amplification from the plasma

Smartphone microendoscopy for high resolution fluorescence imaging [PDF]
, 2016 High resolution optical endoscopes are increasingly used in diagnosis of various medical conditions of internal organs, such as the gastrointestinal tracts, but they are too expensive for use in resource-poor settings. On the other hand, smartphones with

Fluorescence Imaging in Surgery [PDF]
IEEE Reviews in Biomedical Engineering, 2013 Although the modern surgical era is highlighted by multiple technological advances and innovations, one area that has remained constant is the dependence of the surgeon's vision on white-light reflectance. This renders different body tissues in a limited palette of various shades of pink and red, thereby limiting the visual contrast available to the ...
