Nanoparticle delivery of siRNA has problems with penetration and off target accumulation. Here, the authors report on the development of Y-shaped block catiomers which dynamically wrap around siRNA; demonstrate increased circulation times and delivery into hard to reach brain and pancreas tumour models.
