There is an increasing application of quantum dots (QDs) in plant science, as markers for the cells or their cell walls (Cvvs). In a plant cell the CW is a first target place for external agents. We studied interaction of CdSe QDs with CWs isolated from a conifer - Picea omorika (Pant) Purkyne branch. Binding of CdSe QDs was followed by using fluorescence microscopy, fluorescence and FT-IR spectroscopy. The aim of the study was to see whether the QDs induce structural changes in the CW, as well as to find out which kind of interactions between QDs and CVVs occur and to which particular constituent polymers QDs preferably bind. The isolated CW is an appropriate object for study of the interactions with nanoparticles. The results show that in the ON. CdSe predominantly binds to cellulose, via OH groups and to lignin, via the conjugated C=C/C-C chains. The differences in interaction of wet and dry CWs with QDs/chloroform were also studied. In the reaction of the dry CW sample with QDs/chl...oroform, hydrophobic interactions are dominant. When water was added after QDs/chloroform, hydrophilic interactions enable a partial reconstruction of the C=C chains. The results have an implication on the use of the QDs in plant bioimaging.
