Fabrication of a new photoluminescent and pH-responsive nanocomposite based on a hyperbranched polymer prepared from amino acid for targeted drug delivery applications.

In this study, the FeO nanoparticles were encapsulated in the hyperbranched poly -lysine citramid (HBPLC). The FeO-HBPLC nanocomposite modified with -arginine and quantum dots (QDs) to obtain FeO-HBPLC-Arg/QDs as a new photoluminescent and magnetic nanocarrier for the pH-responsive release and targeted delivery of Doxorubicin (DOX). The prepared magnetic nanocarrier was fully characterized using different techniques.
