摘要
Robust cytosolic protein delivery requires both efficient protein binding with delivery vehicles and effective protein release after cell internalization.Although a variety of stimuli-responsive carriers have been designed,simultaneously integrating these two functions in one versatile carrier is challenging.Herein,we developed a polyamidoamine(PAMAM)-based polymer with an intracellular pHactuated hydrophobic-to-hydrophilic transition for this purpose.
