Dextran Fluorescent Probes Containing Sulfadiazine and Rhodamine B Groups

open access: yesMolecules, 2022
Fluorescent imaging has been expanded, as a non-invasive diagnostic modality for cancers, in recent years. Fluorescent probes in the near-infrared window can provide high sensitivity, resolution, and signal-to-noise ratio, without the use of ionizing ...

Fluorescence Imaging in Surgery [PDF]

open access: yesIEEE 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 ...

Fluorescence lifetime imaging [PDF]

open access: yesAnalytical Biochemistry, 1992
We describe a new fluorescence imaging methodology in which the image contrast is derived from the fluorescence lifetime at each point in a two-dimensional image and not the local concentration and/or intensity of the fluorophore. In the present apparatus, lifetime images are created from a series of images obtained with a gain-modulated image ...

Advances in small molecule two-photon fluorescent trackers for lipid droplets in live sample imaging

open access: yesFrontiers in Chemistry, 2022
Two-photon fluorescent trackers for monitoring of lipid droplets (LDs) would be highly effective for illustrating the critical roles of LDs in live cells or tissues.

Fluorescence and Spectral Imaging [PDF]

open access: yesThe Scientific World JOURNAL, 2007
Early identification of dysplasia remains a critical goal for diagnostic endoscopy since early discovery directly improves patient survival because it allows endoscopic or surgical intervention with disease localized without lymph node involvement. Clinical studies have successfully used tissue autofluorescence with conventional white light endoscopy ...

Multispectral Fluorescence Imaging [PDF]

open access: yesJournal of Nuclear Medicine, 2009
Multispectral fluorescence imaging (MSFI) is a rapidly growing field with broad applications in both preclinical and clinical settings. Application of this novel technology in small-animal imaging and microscopy produces enhanced sensitivity and reliable quantification and resolves multiple simultaneous signals.

Fluorescence transformation imaging

open access: yesOptics for Arts, Architecture, and Archaeology VIII, 2021
Fluorescence is a photoluminescence phenomenon where light is absorbed at lower wavelengths and re-emitted at longer wavelengths. For classic artworks, fluorescence gives useful information about varnish and retouches. At the same time, modern artworks may employ synthetic fluorescent pigments because of their special appearance properties, such as ...

An ultrathin fiber-based fluorescent imaging probe based on hyperspectral imaging

open access: yesFrontiers in Physics, 2023
Most fluorescent imaging systems use pre-defined filter sets with limited flexibility in the choice of excitation and emission bands and suffer from crosstalk between different fluorophores for multiplexed imaging.
