^aSize in nm was measured by Zetasizer.

^bZeta potential in mV was measured by Zetasizer.

^cPolydispersity Index was measured by Zetasizer.

Entrapment efficiency of different drugs were measured by HPLC.

Size was measured by DLS using a Zetasizer. The surface charge was also measured by Zetasizer.
