Surface immobilization of engineered hemeproteins: Orientation, stability, structure, and function
Biologically derived macromolecules have drawn great interests for their potentials in biotechnology and material applications. Hemeproteins, including myoglobin, cytochrome b$\sb5$ and cytochrome b$\sb{562}$ that are used in this study, are excellent candidates for the fabrication of novel …

DERIVATIZATION OF DIIMINE TRICARBONYL Re(I) COMPLEXES FOR COOPERATIVE CATALYSIS AND SURFACE IMMOBILIZATION
… molecular templating, physical adsorption, and surface immobilization to promote the binuclear pathway in photochemical CO2 reduction using the Re(I) compounds. In the homogenous approach, we attempted to template dimeric interactions by synthesizing a polymeric Re-amidohexyl compound as well as …

The Development of Microfluidic Devices Fabricated From Poly(dimethyl) Siloxane
… ""chips"" as well as a series of patterns for surface functionalization were demonstrated in PDMS. PDMS proved to be a unique medium for high pH separations allowing the electrophoretic separation of un-derivatized sugars coupled with indirect fluorescence detection. A new microfluidic design …

CD133 Antibody Conjugation to Decellularized Human Heart Valves For Circulating Endothelial Progenitor Cell Capture
… decellularized heart valves with functionalized surfaces capable of rapid in vivo endothelialization have been developed. The aim of this study is to examine the capacity of CD133 antibody-conjugated valve tissue to capture circulating endothelial progenitor cells (EPCs). Decellularized human …

Engineering a highly enantioselective horseradish peroxidase by directed evolution
… enzymatic enantioselectivity based on yeast surface display and fluorescenceactivated cell sorting (FACS). By exploiting the aforementioned method, in just three rounds of directed evolution we both greatly increased (up to 30-fold) and also reversed (up to 70-fold) the enantioselectivity of …

Reactive and soft landing of polyatomic gas-phase ions on plasma-treated metal surfaces
… describes in-situ plasma oxidized dry metal surfaces as novel and advantageous collection targets (plates) for soft landing experiments. A new term, reactive landing, is introduced to cover ion-surface collisions that result in surface immobilization of the impacting ion but without …

MicroCantilever (MC) based nanomechanical sensor for detection of molecular interactions
… study are to investigate the mechanism governing surface stress generation associated with chemical or molecular binding on functionalized microcantilevers. Formation of affinity complexes on cantilever surfaces leads to charge redistribution, configurational change and steric hindrance between …

Poly(p-xylylene) Nanotubes Prepared via the Tubes by Fiber Templates Process as Catalytic Nanoreactors
… or pyrolysis. Accordingly, nanotubes with surface-immobilized catalysts were prepared by coating poly(ethylene oxide) nanofibers with an ethynyl-functionalized PPX. After removal of the template material, the tubes were suitable for “click” chemistry (more precisely, the azide-alkyne …

IMMOBILIZATION AND CHARACTERIZATION OF FLEXIBLE DNAzyme-BASED BIOSENSORS FOR ON-THE SHELF FOOD MONITORING
… as meat and juice are directly in touch with the surface of their containers or covers. Therefore, real-time sensing mechanisms, installed inside the food packaging and capable of tracing the presence of pathogens, are of great interest to ensure food safety. This work involves developing thin, …
