Synthesis of string-bean-like anisotropic titania nanoparticles with basic amino acids

An "assembly-aggregation-peptization" approach is reported for the preparation of colloidal dispersions of string-bean-like anisotropic titania nanoparticles using arginine. These titania nanoparticles have a single-crystalline anatase structure and possess high surface area, which is advantageous for potential functional materials.
