Functionalization of gold nanoparticles for imaging
Jakubechová, Jana ; Pekárková, Jana (referee) ; Drbohlavová, Jana (advisor)
The diploma thesis deals with synthesis of gold nanoparticles and their surface functionalization suitable for in vitro imaging. In this view there are requirements for optical properties such as stability, monodispersity and no presence of cytotocxicity. In order to fulfill these demands the synthesis by Turkevich method with surface modification by glutathione and polytethylenglycol was performed. Analytical methods such as DLS, SEM and Zeta potential measurement were utilized to characterize the physical and chemical properties of synthesized gold nanoparticles. Finally, MTT assay was performed to evaluate toxicity of gold nanoparticles using HEK 293 cell line.

Biofunctionalization of deposited quantum dots
Jakubechová, Jana ; Venerová, Tereza (referee) ; Drbohlavová, Jana (advisor)
The goal of this bachelor thesis is to functionalize the deposited quantum dots (QDs). QDs are prepared thanks to nanoporous alumina template in process of anodic oxidation of Ti film on a silicon wafer followed with modification of gold in process of pulse deposition. The final objective is the subsequent observation of fluorescent properties changes. QDs shows outstanding optical characteristics which can be used for labeling and imaging in biological systems. Thanks to their unique fotostability, they allow long term observation of biomolecules.
