Abstract

The different protein patterns with varied surface coverage are formed by the adsorption of a protein, bovine serum albumin (BSA), on six types of surfaces and characterized with atomic force microscope (AFM). The surfaces include a gold film and five self-assembled monolayers (SAMs) on gold films. Five SAMs are prepared by the immersion of gold plates in solutions: 16-mercaptohexadecanoic acid (MHA), 1-octadecanethiol (ODT), and the mixtures of MHA and ODT at mole ratios of 1:1, 1:10 and 10:1, respectively. The mechanism of protein adsorption on the six surfaces is discussed.
