Nanoscale array biomolecular bond enhancer device

The invention teaches the use of an addressable nanoscale device to create a programmable substrate useful in selectively attracting proteins, nucleating protein crystals and growing protein crystals of a size amenable to diffraction analysis. Further taught is the use of nanoscale assemblies to create charge patterns, where such charge patterns are useful in purifying, nucleating or crystallizing protein molecules. Charge extension moieties, including water, are taught. The invention provides rapid and efficient identification, purification and detection of proteins and protein-related complexes.
