Hydroxyethylmethacrylate/methacrylic acid copolymer cross-linked with ethylenglycol dimethacrylate was prepared by a bulk free radical polymerization method. The permeability studies of this pH-sensitive hydrogel to drugs with different water solubilities showed a water-content dependent diffusion or pore mechanism for ephedrine HCl

In order to develop a versatile model for blood-compatible materials, we studied morphology and platelet adhesion of a dipalmitoyl-phosphatidylcholine (DPPC)/dipalmitoyl-phosphatidylethanolamine-polyethylene glycol (PEG lipid) mixed monolayer. This monolayer, which mimics the cell membrane structure, consists of two heterogeneous layers, that is
