PIC-ing a winner: siRNA encapsulated by a phenylboronate-functionalized polyion complex (PIC) micelle shows binding between the phenylboronate and the 3′ ribose of the siRNA (see scheme), stabilizing the complex under conditions equivalent to the extracellular environment. This complex is disrupted in response to addition of ATP, at a concentration comparable to that inside cells.
