Currently, I am working on surface functionalization of diatom frustules for targeted protein. The purpose of this research is to reduce a series of conventional complicated protein extraction steps to one step protein adsorption. Hence, this project is emphasized to develop a functional group which is highly selective to adsorb protein of interest from complex mixture. Diatom frustules were used as substrate due to its sophisticated nature-design, porous cell wall contains nanostructured which exceeding manufacturing capabilities, reproduced exactness in vast numbers and inexpensive biomaterial. Besides, I am also interested on the colloidal forces involved between the protein and the diatom surface.
