New Cellular Structures Study Findings Recently Were Reported by Researchers at University of California

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Cellular Structures have been published. According to news reporting originating in Berkeley, California, by NewsRx journalists, research stated, "Here we introduce a form of chromatography that can be imposed on the membrane of a living cell. A cell cell signaling interaction is reconstituted in a hybrid live cell-supported membrane junction."

The news reporters obtained a quote from the research from the University of California, "The chromatographic material consists of a hexagonally ordered array of gold nanoparticles (nanodot array), which is fabricated onto the underlying substrate. While individual membrane components move freely throughout the array, the movement of larger assemblies is impeded if they exceed the physical dimensions of the array."

According to the news reporters, the research concluded: "This tactile approach to probing membrane structures in living cells reveals organizational aspects of the membrane environment unobservable by other techniques."
