The reactive conversion of biosilica meso ‐ and nanostrucures into new compositions with retention of shape and fine features is demonstrated. The shape‐preserving nature of the chemical conversion process is illustrated for the reaction of silica‐based diatom frustules with Mg gas to form MgO (see Figure). This technique is promising for the mass production of a variety of low‐cost genetically engineered meso‐ and nanodevices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
