Topography of self-assembled zein structures on hydrophilic and hydrophobic surfaces

Research output: Chapter in Book/Report/Conference proceedingConference contribution


The morphology of zein deposits was examined by atomic force microscopy (AFM) to investigate the effect of environment polarity on structure of zein aggregates. Distinct circular and relatively tall structures, 50 nm high, were observed after rinsing with distilled water. It was found that increasing the environment polarity promoted surface uniformity by inducing hydrophobic interactions between zein and the underlying SAMs. It was also found that rinsing with 75% 2-propanol washed away excess zein leaving a uniform surface of zein molecules attached to the SAMs.
