Paper Abstract

Reported is the use of DNA to template the assembly of nanowires and protein-functionalized nanogap electrodes. Specifically, the use of DNA to template the assembly of gold nanowires between conventionally patterned gold contacts on a silicon wafer substrate. Also the use of DNA to template the assembly of protein-functionalized gold nanogap electrodes on a silicon wafer substrate. Of particular significance is the finding that suitably modified gold nanoparticles recognize and bind selectively the protein-functionalized nanogap between the above electrodes and are localized there. This and related work forms part of a broader effort directed toward the development of the alternative bottom-up fabrication technologies that will be needed to extend Moore's Law beyond 2012.
