In this work, we report the synthesis of aluminum silicate nanoflakes in presence of linear L-arginine amino acid through the sol-gel method. A solution   containing aluminum silicate and hydrochloric acid was prepared and after, L-arginine amino acid was added as template up to gel formation. The gel was dried at 200°C and the powder was characterized by means of X-ray diffraction, scanning tunneling microscopy (STM), electron microscopy (SEM), energy dispersive spectroscopy (EDS), thermogravimetric analysis (TGA), differential thermal analysis (DTA), and IR spectroscopy. The nanostructures’ diameter obtained ranged from 5nm to 50nm with a thickness of about 6nm. The nanoflakes surface area was about  The results show the effect in vitro of L-arginine in the nanoflakes synthesis. These materials can be useful for structured materials, dental materials, and molecular electronics.
