Abstract
We introduce a method for the bottom-up assembly of biomolecular structures that combines the precision of the atomic force microscope (AFM) with the selectivity of DNA hybridization. Functional units coupled to DNA oligomers were picked up from a depot area by means of a complementary DNA strand bound to an AFM tip. These units were transferred to and deposited on a target area to create basic geometrical structures, assembled from units with different functions. Each of these cut-and-paste events was characterized by single-molecule force spectroscopy and single-molecule fluorescence microscopy. Transport and deposition of more than 5000 units were achieved, with less than 10% loss in transfer efficiency.

- A hand-waving argument: Upon separation the binding energy is overcome in the shear geometry within a much shorter distance than in the unzip geometry therefore the force to overcome the energy barrier is much lower in the unzip geometry. Because the forced unbinding of the oligomer in shear geometry is a nonequilibrium process its unbinding force is rate-dependent. In all experiments shown here the duplexes were loaded with a rate of 3000 pN/s.
