Zusammenfassung
Semiconductor quantum dots are a promising class of materials in the
labeling of biological systems. In the present study we show the marking
pattern of Trypanosoma cruzi (T. cruzi) live parasites using PEGylated
CdS/Cd(OH)(2) fluorescent nanocrystals. The analysis obtained by
confocal fluorescence microscopy and transmission electron microscopy
indicates that only the endocytic paths of parasites were labeled. The
parasites were alive after the incubation with the CdS/Cd(OH)(2)-PEG
suspension. Labeling the T. cruzi with quantum dots can help to better
understand the endocytosis process and also the cellular
differentiation. (c) 2008 Elsevier B.V. All rights reserved.
