DNA construction sites

Hermann Gaub at the University of Munich and his team have used AFM cantilevers with attached DNA strands to lift and carry nano components like a nano crane.

If Angela Belcher's virus adaptation method could be sequenced to isolate the peptide components for molecular selectivity those peptides could similarly be placed on an AFM tip and used to pick up a wide range of nanomaterials. Or for that matter an individual virus could be locked into place on a cantilever.

I'm thinking of pick-and-place and machine tool paths here, a selection of tailored cantilevers and carry paths to deliver step-wise precise moieties to a reaction site. The reaction site would be mounted on a NEMS conveyors system to complete a factory scenario.
