Characterization and application of PEO-containing triblock copolymer surfactants

Creator:: Snider, Joshua L.
Abstract:: The action of pendant, polyethylene oxide (PEO) brush layers as nonfouling coatings for biomedical materials is well understood. However progress toward clinical application of stable, high density PEO coatings has historically been impeded by the lack of cost effective, noninvasive methods for their preparation. Triblock polymers featuring a hydrophobic, polypropylene...

Surfactant Effects on Adsorption of Recombinant Factor VIII (rFVIII) at the Air-Water Interface

Creator:: Gray, Warren D.
Abstract:: The primary goal was to characterize the adsorption of a recombinant therapeutic protein in the presence of selected surfactant species at the air-water interface. For this purpose, dynamic interfacial tensiometry was used to determine the surface tension kinetics exhibited by protein solutions containing either Tween 80 or the poly[ethylene oxide]-...

Resistance of adsorbed nisin to exchange with bovine serum albumin, α-lactalbumin, β-lactoglobulin, and β-casein at silanized silica surfaces

Creator:: Muralidhara, Lakamraju
Abstract:: Nisin is an antibacterial peptide, which when adsorbed on a surface can inhibit bacterial adhesion and viability. The ability of noncovalently immobilized nisin to withstand exchange by the milk proteins bovine serum albumin, β-lactoglobulin, α-lactalbumin, and β-casein on surfaces that had been silanized with dichlorodiethylsilane to exhibit high and low...

Nisin adsorption and function at hydrophobic surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] triblock surfactant Pluronic® F108

Creator:: Tai, Yuan-Ching
Abstract:: The adsorption and elution of the antimicrobial peptide nisin at hydrophobic, silanized silica surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]- poly[ethylene oxide] surfactant Pluronic® F108 was measured in situ, with ellipsometry. While such layers are known to inhibit protein adsorption, nisin was observed to adsorb in multilayer quantities, to an...

Synthesis and evaluation of PEO-coated materials for microchannel-based hemodialysis

Creator:: Heintz, Keely
Abstract:: The marked increase in surface-to-volume ratio associated with microscale devices for hemodialysis leads to problems with hemocompatibility and blood flow distribution that are more challenging to manage than those encountered at the conventional scale. In this work, stable surface modifications with pendant polyethylene oxide (PEO) chains were produced on polycarbonate...

Surface tension kinetics of the wild type and four synthetic, structural stability mutants of bacteriophage T4 lysozyme at the air-water interface

Creator:: Wang, Jun, 1968-
Abstract:: Surface tension kinetics exhibited by selected stability mutants of T4 lysozyme at the air-water interface were monitored with DuNoüy tensiometry. Mutant lysozymes were produced by substitution of isoleucine at position 3 with cysteine, leucine, tryptophan and glycine. Each substitution resulted in an altered structural stability quantified by a change in...

The influence of surface functional groups on β-lactoglobulin adsorption equilibrium

Creator:: Al-Makhlafi, Hamood K.
Abstract:: Interactions between proteins and contact surfaces can have important implications in the food industry. Such interactions contribute to the course of fouling of membrane surfaces and they appear to mediate bacterial and spore adhesion to some degree as well. In addition to protein and solution properties, interfacial behavior is strongly...
