摘要:In the past decades, polymeric nanoparticles have emerged as a most promising and viable technology
platform for targeted and controlled drug delivery. As vehicles, ideal nanoparticles are obliged to possess
high drug loading levels, deliver drug to the specific pathological site and/or target cells without drug
leakage on the way, while rapidly unload drug at the site of action. To this end, various “intelligent”
polymeric nanoparticles that release drugs in response to an internal or external stimulus such as pH,
redox, temperature, magnetic and light have been actively pursued. These stimuli-responsive
nanoparticles have demonstrated, though to varying degrees, improved in vitro and/or in vivo drug
release profiles. In an effort to further improve drug release performances, novel dual and multi-stimuli
responsive polymeric nanoparticles that respond to a combination of two or more signals such as
pH/temperature, pH/redox, pH/magnetic field, temperature/reduction, double pH, pH and diols, tem-
perature/magnetic field, temperature/enzyme, temperature/pH/redox, temperature/pH/magnetic,
pH/redox/magnetic, temperature/redox/guest molecules, and temperature/pH/guest molecules have
recently been developed. Notably, these combined responses take place either simultaneously at the
pathological site or in a sequential manner from nanoparticle preparation, nanoparticle transporting
pathways, to cellular compartments. These dual and multi-stimuli responsive polymeric nanoparticles
have shown unprecedented control over drug delivery and release leading to superior in vitro and/or
in vivo anti-cancer efficacy. With programmed site-specific drug delivery feature, dual and multi-stimuli
responsive nanoparticulate drug formulations have tremendous potential for targeted cancer therapy. In
this review paper, we highlight the recent exciting developments in dual and multi-stimuli responsive
polymeric nanoparticles for precision drug delivery applications, with a particular focus on their design,
drug release performance, and therapeutic benefits.
