Bilayer Nanocarriers with Protein–Acid Conjugation for Prolonged Release and Enhanced Anticancer Effects

Conventional chemotherapy, because of the high dose to keep the drug above the minimum effective concentration, possesses severe side effects and brings extra pain to patients. A controlled release drug delivery system, which is a bilayer self-assembled nanoparticle (NP) in this study, can solve this problem. Zein, a biodegradable natural protein from corn, was selected for the first layer of the drug encapsulation. The second layer was formed...
