  • Quantifying nisin adsorption behavior at pendant polyethylene oxide brush layers

    Creator:
    Dill, Justen K.
    Abstract:
    A more quantitative understanding of peptide loading and release from polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. The antimicrobial peptide nisin shows potent activity against Gram-positive bacteria including the most prevalent implant-associated pathogens, its mechanism of action minimizes the...

  • 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...

  • Retention of protein repulsive character and antimicrobial activity of PEO brush layers following nisin entrapment

    Creator:
    Auxier, Julie A.
    Abstract:
    Nisin, an amphiphilic, antimicrobial peptide, has been shown to integrate into the hydrophobic inner region of poly(ethylene oxide) (PEO) brush layers; however, the presence of integrated nisin may compromise the protein repulsive character of the PEO layer. In particular, the introduction of fibrinogen to nisin-loaded brush layers has been observed...
