Acoustically Propelled Nanomotors for Intracellular siRNA Delivery
Abstract
An effective intracellular gene silencing strategy based on acoustically propelled nanowires modified with an interfering RNA's (siRNA) payload is described. The gold nanowires (AuNW) are wrapped with a Rolling Circle Amplification (RCA) DNA strand, which serves to anchor the siRNA therapy. The ultrasound (US)-powered propulsion of the AuNW leads to fast internalization and rapid intracellular movement and hence to an accelerated siRNA delivery and silencing response. To optimize the micromotor gene silencing procedure, the influence of motion, time, and siRNA dosage was investigated, leading up to a 94% silencing after few minutes treatment with US-propelled siRNA-AuNWs, and to a dramatic (∼13-fold) improvement in the silencing response compared to the static modified nanowires. The ability of the nanomotor-based method for gene silencing has been demonstrated by measuring the GFP silencing response in two different cell lines (HEK-293 and MCF-7) and using detailed control experiments. The viability of the cells after the nanomotors treatment was examined using the MCF-7 cancer cell line. The use of DNA structures carried by the US-propelled nanomotors for gene silencing represents an efficient tool that addresses the challenges associated with RNA transportation and intracellular delivery. Future implementation of nanomachines in gene therapy applications can be expanded into a co-delivery platform for therapeutics.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
