A method has been developed to investigate the extent of polymer cross-linking that results following in situ photopolymerization of an acrylate-functionalized phospholipid assembly adsorbed onto a stabilized, membrane-mimetic film produced from a polyelectrolyte multilayer (PEM) on polytetrafluoroethylene (PTFE) grafts. The acrylate phospholipid monomer was synthesized, prepared as a unilamell...
Polyelectrolyte complex micelles have great potential as gene delivery vehicles because of their ability to encapsulate charged nucleic acids forming a core by neutralizing their charge, while simultaneously protecting the nucleic acids from non-specific interactions and enzymatic degradation. Furthermore, to enhance specificity and transfection efficiency, polyelectrolyte complex micelles can ...
Polyampholyte-based films can be efficiently self-assembled onto a surface in a one-pot manner. By using a gradient of protons, morphogens, generated at an electrode surface, a charge-shifting polyelectrolyte present in solution can be transformed into a polyampholyte, leading to the continuous buildup of a film based on polyelectrolyte complexation.
Molecular simulation of the swelling of polyelectrolyte gels by monovalent and divalent counterions.
Permanently crosslinked polyelectrolyte gels are known to undergo discontinuous first-order volume phase transitions, the onset of which may be caused by a number of factors. In this study we examine the volumetric properties of such polyelectrolyte gels in relation to the progressive substitution of monovalent counterions by divalent counterions as the gels are equilibrated in solvents of diff...
among the numerous nanosized drug delivery systems currently under investigation, carbon nanotubes (cnts), regardless of being single or multiple-walled, offer several advantages and are considered as promising candidates for drug targeting. despite the valuable potentials of cnts in drug delivery, their toxicity still remains an important issue. after the pegylation of single-walled cnts (swcn...
