To examine the nanoscale surface architecture of diatom biosilica and replicate its structural features using a synthetic biomimetic model.
Analyzed the microscopic and nanoscopic surface structure of diatom cell walls using various atomic force microscopy (AFM) techniques.
Synthesized artificial silica layers by reacting an aqueous silicic acid solution with tripropylenetetramine in chloroform using a biphasic system.
Atomic force microscopy uncovered an unexpected, distinct granular nanostructure on the surface of natural diatom biosilica cell walls.
Biphasic reaction of silicic acid with tripropylenetetramine yielded thin silica films displaying a granular nanostructure closely resembling native diatom cell walls.
