Glycofunctionalized gold nanoparticles can easily be manipulated as water-soluble macromolecules, highly stable in colloidal solutions. Different nanostructures (see Figure for an example) have been obtained by varying the particle concentration, the Ca2+ level in the solution, and type of oligosaccharide. A potential application of the particle arrays, whose properties resemble those of large biomolecules, is as nanoscale size-selection devices.
