Correction to: Bioreducible Poly(Amino Ethers) Based mTOR siRNA Delivery for Lung Cancer.

abstract：PURPOSE:Targeted delivery of aerosols could not only improve efficacy of inhaled drugs but also reduce side effects resulting from their accumulation in healthy tissue. Here we investigated the impact of magnetized aerosols on model drug accumulation and transgene expression in magnetically targeted lung regions of una...
