An outbreak of Venezuelan equine encephalitis (VEE) that began in northwestern Venezuela in April 1995 has spread westward to the Guajira peninsula and to Colombia (Figure 1), resulting in an… Expand
Force Microscopy – A Tool to Elucidate the Relationship Between Nanomechanics and Function in Viruses
Within the last 20 years nanotechnology has broadened our perspective of different well established disciplines. One of these is virology, which through the development of techniques for the… Expand
Indentation of Highly Charged PSPM Brushes Measured by Force Spectroscopy: Application of a Compressible Fluid Model
Highly charged dense poly(sulfopropyl methacrylate) polyelectrolyte brushes were indented with an atomic force microscopy (AFM) tip as well as with an 8 μm silica colloidal probe at different ionic… Expand
Perfluoroalkylated linear polyglycerols and their supramolecular assemblies in aqueous solution
In this study, amphiphiles composed of linear polyglycerols (LPGs) with hydroxyl, methoxy, and ethoxy side groups and end capped with one or two perfluorooctyl chains (Rf8) have been designed to form… Expand
Lipid Layers on Polyelectrolyte Multilayers: Understanding Lipid-Polyelectrolyte Interactions and Applications on the Surface Engineering of Nanomaterials.
