The essence of nanotechnology is to fabricate and manipulate well-defined structures on the nanometer scale with high accuracy.1 The integration of nanotechnology with material science, bioengineering and traditional lithography fabrication is a powerful route to create advanced, low-cost nanodevices for both optoelectronic and biotechnological applications. Biological molecules, such as DNA, have shown great potential to precisely control functional materials at the scale of individual molecules.2,3 Advancements in this field of study are of interest for the fundamental understanding of the interaction between materials, as well as for the fabrication of more complex electronic circuits. We have successfully assembled 1D DNA nanostructures with high precision via DNA hybridization in situ on properly lithographically patterned and selectively functionalized, surfaces.4 Now we get a step forward towards the controlled and ordered assembly of 1D carbon nanotube from solutions to surfaces.5 Specifically, we explore the binding of single walled carbon nanotube (SWCNT) to lithographically defined nanoscale metal dots anchors,6 which can be selectively functionalized by single stranded DNA (ssDNA) or amine-ended polymers. Fixed-length, DNA wrapped and end-functionalized SWCNT with carboxyl group were indeed attached to nanodot anchors using covalent and noncovalent binding chemistries. Both monovalent and bivalent binding of SWCNT to nanodot pattern are explored. This represents a new approach that could pave the way toward complex SWCNT devices and circuits. References: (1) K. E.
