Self-Organized Materials: From Organic molecules to Genetically Engineered Gold-Binding Proteins

We present examples of ordered assemblies of organic and biological molecules on gold(111) surfaces. The first example shows how control over mono- or multilayer assemblies of 1,4-phenylenedimethanthiol can be achieved and monitored. The second example shows how monolayers on gold can be prepared using amine groups to anchor aromatic molecules to the surface. A third example shows how ordered assemblies of genetically-engineered inorganic-binding polypeptides can be formed on gold surfaces using a 3-repeat, 14 amino acid gold-binding protein (GBP1).
