Facile preparation of succinylated-zein-ZIF-8 hybrid for enhanced stability and pH-responsive drug delivery

Zein nanoparticles have good prospects as a pharmaceutical carrier but limited in further application by its poor stability and re-dispersibility. To obtain high stability and pH-responsive drug delivery, succinylated-zein (Suc-zein) was synthesized by nucleophilic substitution reaction, the material obtained was used to prepare Suc-zein nanoparticles (SZs). The SZs prepared not only had good dispersibility but showed better stability than zein...
