Researchers at Ewha Woman's University Have Reported New Data on Nanoparticles

February 21, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanoparticles. According to news reporting out of Seoul, South Korea, by NewsRx editors, research stated, "Here, we report the formation of polymer vesicles (polymersomes) uniformly decorated with gold nanoparticles (AuNPs) through the interfacial self-assembly of 11-mercapto-1-undecanol (MUL)-stabilized AuNPs and two prototypical amphiphilic polymers (i.e., polystyrene-block-poly(acrylic acid) (PS-b-PAA), poly(ethylene oxide)-block-polylactide (PEO-b-PLA))."

Our news journalists obtained a quote from the research from Ewha Woman's University, "The addition of MUL-capped nanoparticles during the self-assembly process was found to stabilize colloidal polymer assemblies that otherwise tend to form macroscopic aggregates in water. Multicompartment polymersomes with complex internal membrane structures were formed at high nanoparticle volume percent, demonstrating that the interfacial assembly of nanoparticles can be used to create interesting new types of polymer assemblies while providing additional functionalities."

According to the news editors, the research concluded: "This strategy offers a simple method for the formation of nanoparticle-loaded polymersomes that is applicable to various types of amphiphilic polymers."
