Reports Outline Atomic Force Microscopy Study Findings from Ruder Boskovic Institute

January 24, 2014

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Atomic Force Microscopy are presented in a new report. According to news reporting originating in Zagreb, Croatia, by NewsRx journalists, research stated, "Despite many advances in research on photosynthetic carbon fixation in marine diatoms, the biophysical and biochemical mechanisms of extracellular polysaccharide production remain significant challenges to be resolved at the molecular scale in order to proceed toward an understanding of their functions at the cellular level, as well as their interactions and fate in the ocean. This review covers studies of diatom extracellular polysaccharides using atomic force microscopy (AFM) imaging and the quantification of physical forces."

The news reporters obtained a quote from the research from Ruder Boskovic Institute, "Following a brief summary of the basic principle of the AFM experiment and the first AFM studies of diatom extracellular polymeric substance (EPS), we focus on the detection of supramolecular structures in polysaccharide systems produced by marine diatoms. Extracellular polysaccharide fibrils, attached to the diatom cell wall or released into the surrounding seawater, form distinct supramolecular assemblies best described as gel networks."

According to the news reporters, the research concluded: "AFM makes characterization of the diatom polysaccharide networks at the micro and nanometric scales and a clear distinction between the self-assembly and self-organization of these complex systems in marine environments possible."
