“…In an attempt to understand how polymerization of vesicles affected the metal synthesis and yield efficiency, we investigated the synthesis of gold particles using unpolymerized vesicles comprised of similar phospholipid mixtures and reported the effect of temperature processing on the size and shape of the particles (20). In that work, we observed that the gold particles, synthesized at close to equilibrium conditions, were faceted and multiply twinned.…”

“…Gold was chosen as the synthetic target in this study due to its chemical stability. We previously reported that the size range of redispersed gold nanoparticle powders synthesized via surfactant membranes comprised of mixtures of charge neutral diacetylenic phosphocholine and palladium ionbound negatively charged diacetylenic lipids differed depending on the processing temperature (20). At 25°C particle size ranged from 16 to 25 nm while at 40°C particle size ranged from 30 to 150 nm.…”

“…Several procedures have been reported in these uni-or multilamellar vesicles. A significant amount of AuNPs but inhomogeneous in shape and size was obtained using classical reducing agent (Chow et al, 1996). However, the gold nanoparticles were also generated in the run without a reducing agent.…”

Noble metal nanoparticles are important subjects in the field of nanotechnology. Various synthetic processes have been summarized and discussed for the preparation of noble metal nanoparticles of different sizes, shapes and solubility. Among them the colloidal fluids are most fascinating. The formation of nanoparticles starts by the reduction of metal salt and continue with the agglomeration of metal atoms to embryos, subnanoparticles and to premature metal nanoparticles. The existence of the microenvironments in the colloidal systems gives nanoparticles unique reactivity towards various molecules and additives. A soft template can be applied to synthesize noble metal nanoparticles in different-shaped biomolecules-based nanoreactors, micelles and liposomes. The size and shape of nanoparticles follows reactant feed composition, reaction conditions, presence or absence of template and type and concentration of reactants.

“…11 Yet, despite such advantages, previous attempts at synthesizing AuNPs within liposomes have resulted in high size polydispersity, inhomogeneity in shape, or poor yield. [12][13][14] Recently, the synthesis of AuNPs within liposomes was achieved by the controlled diffusion of stabilizing agents into encapsulated gold salt solutions, 15,16 or by doping the lipids that constitute a liposome with glycerol that acts as a reducing agent. 17 However, these approaches have had the need to either modify the method of liposome preparation or use special lipids to achieve controlled synthesis of AuNPs.…”
