摘要: Acombinatorial strategy based on nucleic acid assembly and electrostatic complexation is developed for efficient small interfering ribonucleic acid(siRNA) delivery. In this approach, siRNAs are first loaded into a well-defined nanotube through programmable nucleic acid self-assembly. Compared to small rigid siRNA duplex, the obtained siRNA-bearing nanotube with large architecture is more readily to complex with cationic and ionizable poly(β-amino ester), resulting in the formation of a novel platform for efficient siRNA delivery.
