PhD Project: Surface Modification via Click-Type Reactions induced by Microcontact Chemistry

Abstract of Research Project

Microcontact Chemistry is a variation of microcontact printing and employs microstructured elastomeric stamps for the transfer of “molecular inks” onto surfaces functionalized with complementary moieties by initiating chemical reactions site-specifically. This technique features a number of advantageous properties such as a wide substrate scope concerning surface materials and molecular inks, short patterning times, low consumption of ink, high pattern resolutions and large area patterning. This is why microcontact chemistry emerged as a powerful tool for the preparation of patterned functional surfaces and proved to be applicable for the manufacturing of e.g. DNA, RNA and carbohydrate microarrays as well as for the immobilization of proteins and cells. The project’s aim is to apply click-type reactions in combination with microcontact chemistry on self-assembled and polymeric surfaces in order to obtain advanced surface modifications. The success of these functionalizations will be verified by different analytical tools such as fluorescence microscopy imaging, X-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, atomic force microscopy and surface plasmon resonance spectroscopy.
