Abstract

A method of synthesizing corrugated and nanoporous microspheres including the steps of synthesizing substantially smooth spherical microspheres, and controlled wet-etching of the substantially smooth spherical microspheres with a basic solution having a pH above 10.00 is provided. The microspheres can include, for example, silica microspheres or titania microspheres of various sized diameters of between 50 nm and 600 nm. The basic solution can include an aqueous potassium cyanide solution or an aqueous potassium hydroxide solution. Methods of using the corrugated and nanoporous microspheres described herein are also provided.
