Design of biocompatible chitosan microgels for targeted pH-mediated intracellular release of cancer therapeutics.

abstract：:The complement system plays an important role in innate and adaptive immunity, which suggests that complement activation could be exploited as a potential strategy for vaccine adjuvants. Here we explored the potential of chitosan-based microparticles (CS-NH2 MPs) as a vaccine adjuvant with an active surface for comple...
