Most nanoscale components today are made by top-down processes, like lithography, where smaller structures are created from a larger starting block. Such techniques are routinely employed in the semiconductor industry but the goal of nanotechnology is to build tiny devices from the bottom up, which is much more challenging. Researchers in Germany have now shown that their “single-molecule cut-and-paste” technique can be used to make protein-DNA chimeras for such nano-assembly and to study the fundamental behaviour of biomolecules such as proteins…….
