The Preparation and Characteristics on Chitosan Nano-Carrier with Different Concentration of TPP

Abstract:

Article Preview

In this Study, the Tripolyphosphate-Chitosan (TPP-CS) Nano-Carrier was Prepared by Polyelectrolyte Complexation. TPP and CKGM are Polyanion, and can Interact with Cationic Chitosan by Electrostatic Forces. the Nanoparticles Size was Analyzed by the Transmission Electron Micrographs (TEM) and Scattering Electron Micrographs (SEM). FTIR Confirmed Tripolyphosphoric Groups of TPP and CKGM Linked with Ammonium Groups of Chitosan in the Nanoparticles. the CS Nps were Loaded with the Anticancer Drug, Berberine, by Different Concentration of Cross-Linking Agent. the Zeta Potentials of CKGM and CS were Shown as a Function of Ph. it was Observed that CS has Strong Interaction with CKGM about Ph 5.5. the CKGM-CS Nanoparticles were Formed by Mixed Different Weight Ratio of CS and CKGM. the Morphology of CKGM-CS was Characterized by FESEM. the Size of CKGM-CS Particles was Smaller than 150 Nm. the Zeta Potential of CKGM-CS Particles was Proved that the Polymer Ratio can Control the Charge Density.
