Název v původním jazyce

In Vivo Fluorescence Visualization of Quantum Dot Nanoparticles in Plants

Popis výsledku v původním jazyce

Visualization of nanoparticles can be exceedingly useful in tracking of targeted drug delivery systems. For this purpose, highly luminescent quantum dot nanoparticles may represent a suitable option due to their superior photophysical properties and versatile surface chemistry. This study was mainly focused on application of CdTe quantum dot nanoparticles for fluorescence imaging of their transport in plants. In vivo experiments were carried using leaves of sunflower plant (Helianthus annuus). Leaves, soaking water solution of CdTe-PVP and CdTe/ZnS quantum dots, were monitored (ʎem 535 nm and 600 nm respectively) for 8 hours at time intervals of 60 minutes using In Vivo Xtreme Imaging System (Bruker, MA, USA). Autofluorescence of biomolecules present in plants, including chlorophyll, carotene and xanthophylls, represents a crucial problem in fluorescence imaging of plants. However, by using adequate excitation and emission filters during fluorescence images acquisition, this phenomenon can be effectively suppressed. Moreover, multispectral imaging and spectral modelling can be performed in order to distinguish fluorescence of quantum dots. In this study, a comparison of two different modifications of CdTe quantum dots is provided together with recommendations on setting of appropriate excitation and emission range for image acquisition.
