Abstract

Select embodiments of the present invention employ biological means to direct assemble CNT-based nanostructures, allowing for scaling to macrostructures for manufacture. In select embodiments of the present invention, a method is provided for assembling DNA-functionalized SWNTs by phosphodiester bonding catalyzed by ssDNA-ligase to form macroscopic CNT aggregates.
