Novel Tumor Targeting Near Infrared Fluorescent Probes
Advances within the field of in vivo optical imaging have added an arsenal of powerful tools for monitoring tumor development non-invasively in preclinical cancer models (Contag et al., 1997). Bioluminescence allows both, sensitive and rapid analysis of light emitted from luciferase-labeled cells and can be used to measure tumor burden from otherwise non-visible deep tissue locations when calip...
متن کامل[Development of near-infrared fluorescent probes for in-vivo imaging].
The number of reports on new techniques in molecular imaging has been recently increasing because of their usefulness in biological, medical, and clinical research. Fluorescence imaging methods are generally superior in terms of sensitivity, selectivity and ease of use. Cyanine dyes have been employed as fluorescent labels in fluorescence imaging studies of biological mechanisms. In particular,...
متن کاملSynthesis and evaluation of polyhydroxylated near-infrared carbocyanine molecular probes.
[reaction: see text] A new near-infrared (NIR) fluorescent molecular probe derived from indocarbocyanine dye and galactose was prepared, and the procedure was optimized. The presence of a nonionic polyhydroxyl moiety between hydrophobic groups enhances solubility and possibly minimizes aggregation in aqueous solutions. The structural framework of this molecule provides multivalent sites for lab...
متن کاملImaging bacterial peptidoglycan with near-infrared fluorogenic azide probes.
Fluorescent probes designed for activation by bioorthogonal chemistry have enabled the visualization of biomolecules in living systems. Such activatable probes with near-infrared (NIR) emission would be ideal for in vivo imaging but have proven difficult to engineer. We present the development of NIR fluorogenic azide probes based on the Si-rhodamine scaffold that undergo a fluorescence enhance...
متن کاملNew near-infrared optical probes of cardiac electrical activity.
Styryl voltage-sensitive dyes (e.g., di-4-ANEPPS) have been widely and successfully used as probes for mapping membrane potential changes in cardiac cells and tissues. However, their utility has been somewhat limited because their excitation wavelengths have been restricted to the 450- to 550-nm range. Longer excitation/emission wavelength probes can minimize interference from endogenous chromo...
