ACKNOWLEDGMENTS

I have the opportunity to express my gratitude to my supervisor Prof. Dr. Hermann Wätzig for
contributed time, constructive discussion, and suggestion during this study.
It is a great pleasure to extend thanks to the members of the examination committee for
constructive comments and reviewing this thesis.
I would like to thank to the member and colleagues of the institute of Pharmaceutical
Chemistry, TU-Braunschweig, especially to Dr. Michael Graf, Dr. Sami El Deeb, Heidi
Köppel, Phillip Hasemann, Simone Schröder, Lukas Kaminski, Sascha Kühne and Xi Deng.
I am deeply thankful to Sascha Kühne for carefully reading this thesis.
I wish to extend my gratitude to the Germany Academic Exchange Service (DAAD) for
financial support.
My grateful thanks are also for Department of Microsystems Engineering (IMTEK), Albert-
Ludwigs Universität Freiburg (Breisgau) for providing polydimethylacrylamide (PDMAA)-
coated capillaries and Polymicro Technologies (Phoenix, AZ, USA) for providing bare fused-
silica and polyacrylamide (LPA)-coated capillaries used in this research.
