✦ Synopsis

Films formed by the deposition of solutions of Bovine Serum Albumin (BSA) in the presence of various sodium salts have been investigated by both Optical and Atomic Force Microscopy, with the aim of assessing the effects of anion recognition on the micro-structuring of such films. Depending on the anion present the structures formed vary from dendritic spherulite structures, through block structures to pseudo-dendritic 'devil's comb' structures. The angular orientation of these structures depends strongly on the nature of the anion. The effects of the film processing temperature have been investigated and in the case of the nitrate anion shows notable changes both in spacing and orientation of the dendritic structures.
