    Abstract: The present invention relates to methods for self-assembly of arbitrarily-shaped metal nanostructures using specifically-designed patterns on nucleic acid scaffolds. The methods involve using the nucleic acid scaffolds as templates on which a second material patterned, as seed nuclei. The patterns are then selectively plated with metal using an electro-less plating process to create arbitrarily-shaped metal nanostructures that are not constrained by the structure of the scaffold. The methods herein use controlled-growth processes to actively select the dimensions, positions, and alignments of the patterns to create different arbitrary shapes of metal nanostructures.

    Abstract: The invention provides compositions and methods for signal activated RNA interference (saRNAi), preferably in vivo. The invention provides polynucleotides that switches between an inactive form and an active form upon covalent or non-covalent interaction with one or more specific chemical signals, such as disease-specific mRNA, miRNA, or other cellular RNA products with sequences that characterize diseased states of the cell. The interaction between the subject polynucleotides and the signals is preferably mediated by hybridization, which exposes, facilitates the formation, and/or allows the formation of a substrate that can be processed by proteins of the RNAi pathway (such as Dicer). The input and output of multiple different polynucleotides of the invention can form an in vivo signaling network. In addition, the multiple input signals can be integrated to modulate the activity of the subject polynucleotides.
