Recent Findings from National University Has Provided New Information about Chemical Engineering

February 12, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Chemical Engineering. According to news reporting originating in La Plata, Argentina, by VerticalNews journalists, research stated, "Ferrogels with well-dispersed single-domain magnetic nanoparticles (NPs) were obtained by the infusion of iron salts in physically cross-linked poly(vinyl alcohol) (PVA) hydrogels followed by coprecipitation. Freeze-thaw (F-T) cycling was used as a cryogenic technique to form mechanically strong and highly swellable hydrogels."

The news reporters obtained a quote from the research from National University, "The networked structure of the final material was used as a constrained environment for the precipitation of iron oxide NPs and formation of the magnetic gel. A homogeneous, single-domain ensemble of more than 15 wt % iron oxide NPs (in only one cycle of absorption) could be obtained through this easy technique. Moreover, the capacity of these magnetic ferrogels to absorb high amounts of ethanol/water solutions allows impregnation of these materials with ibuprofen and subsequent release of the drug at physiological pH."

According to the news reporters, the research concluded: "The biocompatibility of the components and the use of the nontoxic PVA cross-linking strategy (F-T cycling) make these materials promising for drug-delivery applications."
