microPET-based biodistribution of quantum dots in living mice.
UNLABELLED This study evaluates the quantitative biodistribution of commercially available CdSe quantum dots (QD) in mice. METHODS (64)Cu-Labeled 800- or 525-nm emission wavelength QD (21- or 12-nm diameter), with or without 2,000 MW (molecular weight) polyethylene glycol (PEG), were injected intravenously into mice (5.55 MBq/25 pmol QD) and studied using well counting or by serial microPET a...
متن کاملParticle size, surface coating, and PEGylation influence the biodistribution of quantum dots in living mice.
This study evaluates the influence of particle size, PEGylation, and surface coating on the quantitative biodistribution of near-infrared-emitting quantum dots (QDs) in mice. Polymer- or peptide-coated 64Cu-labeled QDs 2 or 12 nm in diameter, with or without polyethylene glycol (PEG) of molecular weight 2000, are studied by serial micropositron emission tomography imaging and region-of-interest...
متن کاملBiodistribution And Clearance Of Quantum Dots In Small Animals
INTRODUCTION The many potential biomedical applications of QDs have been recently and extensively reviewed elsewhere, but progress is currently impeded by a lack of understanding of how nanostructures interact with biological systems [2]. All of the reports in the literature were unanimous in concluding that QDs show a preference for deposition in organs and tissues and that they do not remain ...
متن کاملIn vivo biodistribution and behavior of CdTe/ZnS quantum dots
The unique features of quantum dots (QDs) make them desirable fluorescent tags for cell and developmental biology applications that require long-term, multitarget, and highly sensitive imaging. In this work, we imaged fluorescent cadmium telluride/zinc sulfide (CdTe/ZnS) QDs in organs, tissues, and cells, and analyzed the mechanism of their lymphatic uptake and cellular distribution. We observe...
متن کاملApplications of Quantum Dots in Cell Tracking
Tracking cells after transplantation is always one the main concerns of researchers in the field of regenerative medicine. Finding a tracer with long stability and low cytotoxicity can be considered as a solution for this issue. Semiconductor nanocrystals, also called quantum dots (QDs), have unique photophysical properties which make them as suitable candidate in this setting. Broad-range exci...
