This is an abstract for a presentation given at the
10th Foresight Conference on Molecular Nanotechnology


Both branched and linear DNA scaffolds can be used in the methyltransferase-directed targeting of fusion proteins. These self-assembling biostructures are easily studied, and microfluidic-chip-based analysis greatly facilitates their detection and analysis. Our experience with these systems suggests that the technology is only limited by the yield of high occupancy structures. Linear and branched biostructures containing three targeted proteins have been reliably prepared. This permits the construction of a variety of open and closed assemblies that can be designed as static or dynamic systems. Macromolecular structure-locks, rotaxanes, carcerands, and switches may find a variety of applications in biology, nanoscience and nanotechnology.
