Cysteine modified and bile salt based micelles: Preparation and application as an oral delivery system for paclitaxel

- A type of polyion complex micelles was constructed through the electrostatic interaction.
- Drug-loading capacity of PF127-CS/PF127-cysteine/NaC micelles was increased significantly.
- The oral bioavailability of micelles was five times greater than that of the paclitaxel solution.
