Gold Nanoparticles: Small 9/2009

The cover picture illustrates hierarchical nanostructures. Hexagonally ordered gold nanoparticle arrays with an interparticle distance of tens to hundreds of nanometers are micropatterned by conventional UV or electron-beam lithography. In the next step, gold nanoparticles are used as anchor-points to attach recombinant proteins allowing for the control of protein presentation at two different length scales. For more information, please read the Communication “Micro-Nanostructured Protein Arrays: A Tool for Geometrically Controlled Ligand Presentation” by J. P. Spatz et al., beginning on page 1014.
