| Description: | Lipid monolayers at planar aqueous solution-vapor and solution-substrate interfaces provide an ideal platform for facilitating two-dimensional(2D) assembly of biomolecular nanoparticles like proteins and virus particles. In order to illustrate the utility and versatility of this approach to promoting the ordered assembly of nanoscale objects, we will describe the results of two of our recent studies: (i) the effects of surface biotin density on the 2D crystallization of the soluble protein streptavidin, and (ii) the electrostatic 2D assembly of virus particles, with emphasis on cowpea mosaic virus (CPMV). The structures of these systems have been probed by synchrotron x-ray scattering (GISAXS & XR), AFM, and optical microscopy measurements. We will also illustrate the capability of these techniques for in-situ characterization of structures at liquid interfaces. |
