In this communication, we report the synthesis of chitosan (CS, a biodegradable and biocom- patible natural polymer) [1] nanoparticles as drug carriers by ionic gelation. The method is based on ionic interactions between positively charged groups NH3 + of CS (in dilute CH3COOH solution) and negatively charged of sodium tripolyphos- phate, TPP).
