Abstract
Self-assembly of the amphiphilic copolymer into core–shell-like nanoparticles is the new tactic to tailor carriers toward rationalization in the field of drug-delivery systems. Herein, a facile route for examining how the entrapment of a hydrophobic and negative-charge drug affects the micellar structure of a positive-charged copolymer and its biological behavior was developed. In this study, Pluronic F127-grafted chitosan (CF127) was utilized as a positive-charged copolymer for in situ loading of nanocurcumin in a cosolvent condition. Ultrasonication was found to be an effective method to control the self-assembly of phosphocasein and its interaction with curcumin. The superstructure of the incorporated nanoparticles was fabricated in the medium under unimolecular micelles as vesicular structure (SV) at lower ultrasonic condition while large complex micelles (multimicelle aggregates, LCMs) at higher ultrasonic power density. According to transmission electron microscopy, variable UV–visible spectrophotom...
