“…Thereafter, upon increasing phospholipid concentration in the mixtures, the van der Waals attraction between the phospholipid layer on latex and free vesicles in the dispersion would drive deposition of a phospholipid bilayer onto the monolayer covered latex (Carmona-Ribeiro & Herrington, 1993). The lipid coveredlatexes are useful as hosts for receptors (Sicchierolli & Carmona-Ribeiro, 1995;Sicchierolli & Carmona-Ribeiro, 1996;Moura & Carmona-Ribeiro, 2006), reduced protein adsorption on the polymer (Sicchierolli & Carmona-Ribeiro, 1996) and chromatography (Hautala et al, 2003;Haratake et al, 2007;Gulcev & Lucy, 2008). Although DODAC or DHP electrostatically adsorbed to oppositely charged polystyrene microspheres, forming homodisperse bilayer -covered latices, this took place only over a certain range of low lipid concentration.…”
