Investigation of Unilamellar Phospholipid Vesicle Interactions with PNIPAM Based Hydrogel Beads

MacKinnon, Neil J. 03 March 2010 (has links)
Phospholipid liposome binding to hydrogel beads based on poly(N-isopropylacrylamide) (PNIPAM) is accomplished employing either avidin/biotin conjugation or hydrophobic modification of the microgels, and the ability to form single supported lipid bilayers is explored. The co-monomer acrylic acid (AA), evenly distributed or localized to the shell of the microgel, is included to facilitate post-polymerization chemical modification of the hydrogel beads. The degree of chemical modification of the microgels as well as the thermal behavior is monitored via 1H and 13C nuclear magnetic resonance (NMR). Liposomes composed of 1-palmitoyl-2-oleoyl-sn-glycero-3-phoshocholine (POPC) and a small amount of commercially available biotinylated-lipid are shown to bind as intact entities while sequestering internal contents to biotinylated hydrogel beads, utilizing avidin as the coupling agent. Under fusogenic conditions, these bound liposomes remain as individual vesicles. Alternatively, POPC liposomes are shown to bind to microgels modified to display single chain alkyl groups or cholesteryl moieties, and remain as intact vesicles. It is demonstrated that these liposomes become permeable at high hydrophobe content. Bound liposomes will fuse into larger structures under high hydrophobe content conditions, but remain permeable. The volume phase transition (VPT) characteristic of PNIPAM microgels is shown to influence the permeability of hydrophobically bound (low hydrophobe content), but not avidin/biotin conjugated, liposomes. The degree of liposome binding, as well as their resulting structures and permeability are investigated utilizing 31P NMR, fluorescence spectroscopy and microscopy. The microgel-bound liposome and microgel-supported lipid bilayer hybrid systems would be ideally suited to drug delivery and tissue engineering applications. The microgel-supported single lipid bilayer system would, in addition, potentially act as a cell model system for membrane dynamics and embedded amphiphile NMR studies.
