Abstract: Disclosed herein are programmable, conditionally activated small interfering RNA constructs (Cond-siRNAs) and methods of making and using the same as therapeutic agents. The Cond-siRNA comprises a sensor strand, a core strand, and a guide strand, which crossover to form a sensor duplex and a RNAi duplex attached to each other to form a single structure. Upon binding an input strand to the sensor strand, the Cond-siRNA is activated and releases RNAi targeting a desired gene.

Abstract: Disclosed herein are multi-way oligonucleotide junctions for delivering one or more cargo molecules to a biological target and method of making such junctions. The oligonucleotide junctions are formed by two or more oligonucleotides and are stable outside the cell and easily dissociate inside the cell to release the cargo molecule(s). One or more cargo molecules as well as delivery ligand can be loaded to the junctions for targeted delivery. Also disclosed are nanostructures including one or more junctions attached to each other for delivering two or more cargo molecules.

Abstract: Provided herein are signal activatable molecular constructs for delivery of molecules and related components, compositions, methods, and systems, having a 17 to 30 bp targeting domain duplex RNA, at least one protection strand having a protection segment and linker segment and a sensor strand having a displacement segment and a toehold segment, in which in an inactive conformation the protection segment and the displacement segment form a sensor domain duplex polynucleotide covalently attached to the targeting domain and presenting the toehold segment for binding to a signal molecule. In an active conformation the sensor strand is bound to the signal molecule and is detached from the at least one protection strand and from the targeting domain; and the targeting domain attaches the at least one protection strand in a configuration allowing processing by Dicer and/or an Argonaute enzyme.

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.

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.
