Investigators at Institute for Health and Consumer Protection Zero in on Nanoparticles (Detection of silver nanoparticles inside marine diatom Thalassiosira pseudonana by electron microscopy and focused ion beam)

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Nanoparticles are discussed in a new report. According to news reporting originating in Ispra, Italy, by NewsRx journalists, research stated, "In the following article an electron/ion microscopy study will be presented which investigates the uptake of silver nanoparticles (AgNPs) by the marine diatom Thalassiosira pseudonana, a primary producer aquatic species. This organism has a characteristic silica exoskeleton that may represent a barrier for the uptake of some chemical pollutants, including nanoparticles (NPs), but that presents a technical challenge when attempting to use electron-microscopy (EM) methods to study NP uptake."

The news reporters obtained a quote from the research from Institute for Health and Consumer Protection, "Here we present a convenient method to detect the NPs interacting with the diatom cell. It is based on a fixation procedure involving critical point drying which, without prior slicing of the cell, allows its inspection using transmission electron microscopy."

According to the news reporters, the research concluded: "Employing a combination of electron and ion microscopy techniques to selectively cut the cell where the NPs were detected, we are able to demonstrate and visualize for the first time the presence of AgNPs inside the cell membrane."
