Spatial and temporal estimation of nanomechanical properties via Atomic Force Microscopy
… A diverse set of applications ranging from polymeric surfaces to protein assembly are studied using this method. In addition to uncovering fundamental surface properties, the groundwork for applying nanomechanical identification for new applications such as forensic identification for …

Micro- and nano-scale polymer-on-polymer stamping of the polyelectrolytes SPS and PDAC
… have been small, reactive molecules patterned on surfaces they are chemically attracted to, like thiols on metals or silanes on glass and metal oxides. Our group has introduced a new approach to surface patterning by using polymers to pattern polymeric surfaces. To further expand the options of …

Nanoscale Investigation of Adhesion, Friction, and Wear in Chemically Heterogeneous Responsive Polymer Brushes
Polymer brushes provide the responsive smart surfaces which can be used for fabrication of various devices. In this thesis work, adhesion, friction, and wear of polystyrene (PS) - poly(2-vinyl pyridine) (P2VP) and polystyrene - poly(acrylic acid) (PAA) binary brushes and corresponding monobrushes …

Fremdschichtverhalten nanostrukturierter superhydrophober Isolierstoffoberflächen unter simultanen elektrischen und klimatischen Beanspruchungen
Polymeric insulating materials can exhibit a significant self-cleaning effect (superhydrophobicity) after their surfaces are treated by a naonstructured hydrophobic layer. These housing materials are of great interest for an application in electrical insulation systems, because water droplets, …

Spatially controlled engineering of myocardial tissue
… adhesion and organization of cardiomyocytes on polymeric surfaces such that they exhibited a more mature and fully differentiated phenotype. Morphological features of native myocardium, such as the dimensions of individual cardiomyocytes, myofibril assembly and organization, intercalated disk …

Investigating The Relationship Between Surface Topology And Functional Characteristics For Injection Moulded Thermoplastic Components
Bacteria are known to adhere to surfaces, which allows for the formation of biofilms, possibly causing a surge in hospital-offset infections, perilous diseases, and in some cases, death. Although certain bacteria are present in the natural flora of the human skin, some present extreme clinical …

Toll-like receptor mediated responses to adsorbed damage-associated molecular patterns on biomaterial surfaces
… The in vitro data showed that adsorbed DAMPs on polymeric surfaces, both alone and in the presence of blood proteins, strongly induced NF-B/AP-1 transcription factor activity and pro-inflammatory cytokine secretion in reporter macrophages, compared to serum- and plasma-adsorbed surfaces. …

Design and microfabrication of multifunctional bio-inspired surfaces
… hierarchical multifunctional bioinspired surfaces. Different natural surfaces have been surveyed including well-known lotus leaf, sharkskin, back of the Namib Desert beetle, butterfly wings, and legs of water-walking insects. The lotus leaf features superhydrophobicity, which leads to low …

Surface modification of silicon photonic microring resonators for chemical sensing
… many chemistries compatible with silicon dioxide surfaces, but the two presented within, hydrogels and polymer brushes, lend the researcher unique control over the platform’s chemical and physical properties. Hydrogels, in particular poly(acrylamide) and poly(acrylic acid), have well-defined …
