Molecular and Biofunctional Modification of Conformal POEGMA Bottlebrush Coatings and Applications Toward In Vitro Diagnostics
… depends considerably on the quality of the assay surface being used and the steps/reagents required to complete the assay. Synthetic “bottlebrush” polymers have garnered considerable attention as molecularly defined and tunable biointerfacial coatings for a diverse set of biomedical applications; …

Development of Mesoporous Silicas, Responsive Polymer Microgels, and Related Nanocomposites
… brushes were successfully grafted from the surface of hollow silica nanospheres via surface-initiated atom transfer radical polymerization with activators regenerated by electron transfer (SI-ARGET ATRP), and the polymer loading was well controlled. Besides, the core-shell-structured …

POLY(N-ISOPROPYL ACRYLAMIDE)-COATED SURFACES: INVESTIGATION OF CYTOTOXICITY WITH MAMMALIAN CELLS AND THE MECHANISM OF CELL DETACHMENT
… the (possibly) cytotoxic polymer would be transferred to implanted engineered tissues. In this work, we present an investigation of the cytotoxicity of pNIPAM-grafted surfaces, as well as an investigation of the mechanism of cell detachment from pNIPAM. The cytotoxicity of substrates …

Toward spatial control of gold nanorod surface functionalization
… The resonant generation of a localized surface plasmon resonance (LSPR) at the GNR surface results in interesting optical properties and unique interactions with molecules. Combined with their biocompatibility, ease of synthesis and facile surface functionalization, these anisotropic …

Polymers as directing agents for motions of chemical and biological species
This thesis involves descriptions of solid surface modifications with various polymeric materials which were used as a guiding agent for motion of chemical and biological species. Quasi-two dimensional poly(oligoethylene glycol) acrylate polymer brush based molecular conduits have been designed …

Surface modification of silicon photonic microring resonators for chemical sensing
… and at low concentrations. Functionalizing the surface of silicon photonic microring resonators with covalently bound organics is one detection strategy to both increase detector sensitivity (by localizing the analyte within the organic layer) and lend a degree of selectivity in the partitioning …

Towards Mechanical Reinforcement in Polymer Layered Silicates Nanocomposites of the Second Generation
… planes to realize stiffer platelets with higher surface area. Moreover, the larger diameter of the nanoplatelets is beyond the size of typical microcracks and the number of platelets acting as stress concentrators is two orders of magnitude lower at any given filler content. The synthetic …

Janus Particles at Interfaces
… wettability, biocompatibility, flexible surface chemistry, increased chemical stability are implemented together with a thermo-responsive polymer corona. On the basis of our well-characterized core-shell particles we took advantage of the variable surface chemistry of the silica shell to …

Synthesis and kinetic processes in designed polymers
… and regulated substances. By functionalizing the surface of silicon photonic microring resonators with polymer brushes, we find that small molecules can selectively partition into the surface-confined sensing region of the optical resonators. This strategy leads to response enhancements in excess …
