Abstract:

RNAi has always captivated scientists due to its tremendous power to modulate the phenotype of living organisms. This natural and powerful biological mechanism can now be harnessed to down-regulate specific gene expression in diseased cells; opening up endless opportunities. Since most of the conventional siRNA delivery methods are limited by a narrow therapeutic index and significant side and off-target effects, we are now in the dawn of a new age in gene therapy driven by nanotechnology vehicles for RNAi therapeutics. Here, we outlook the "do's and dont's" of the inorganic RNAi nanomaterials developed in the last 15 years and the different strategies employed are compared and scrutinized, offering important suggestions for the next 15.
