Abstract
A big challenge for molecular electronics is the development of a viable technology that will allow billions of molecular or nanoelectronic components to be assembled and interconnected into useful logic/memory devices and systems. Size reduction is not the only goal of nanotechnology; nanodevices with higher order photonic, sensory, chemical, catalytic, and therapeutic properties are also envisioned. Presently, the barrier to the development of such devices and systems is organizing components for this higher level functioning, rather than the availability of the molecular components.
This talk will present active microelectronic DNA arrays for applications in genomic research and DNA diagnostics. These active microelectronic devices have the ability to create almost any electric field transport geometry on the array surface, which then allows charged reagent and analyte molecules (DNA, RNA, proteins, enzymes), nanostructures, cells and micron-scale structures to be moved to or from any of the microscopic test sites on the device surface.
This talk will also present two potential applications of this principle of an "electronic pick and place" process: (a) heterogeneous integration of various microfabricated lift-off components (lasers, diodes, etc.) into integrated photonic and electronic devices (displays, arrays, etc.), and (b) a DNA chromophore based optical storage material that uses chromophoric DNA self-assembly for applications in high density optical data storage. In the longer term, the electronic pick and place process will be used to carry out the nanofabrication of highly integrated molecular electronic circuits and devices.
