Abstract : This report summaries our accomplishment in the area of DNA-based nanofabrication, supported by ONR grant N00014-13-1-0575. During the funding period, our research produced 21 peer-reviewed journal publications and 23 conference presentations/invited talks. Specifically, we have: (a) Studied the water adsorption on DNA origami template and its impact on DNA-mediated chemical reactions. We also extended the concept of DNA-mediated reaction to other nanoscale templates, (b) Studied the thermal and chemical stability of DNA origami template. The result shows that the DNA nanostructures can be potentially used in very harsh chemical environments, (c) Studied the effect of DNA origami template on the growth of self-assembled monolayer (SAM) structure. We developed a method to produce nanoscale patterns on SAM. (d) Studied the molecular imprinting of DNA origami structure using polymer substrates. Developed a high-resolution pattern transfer approach to pattern polymer surfaces, (e) Evaluated precursors for solution deposition of CdE (E = S, Se, and Te) semiconductors onto a DNA template, (f) Studied the wettability of graphitic carbon materials and its impact on the interaction between graphitic substrate and DNA nanostructures.
