Abstract

---

Due to the vital contribution of Nanotechnology science in advancement of various industries, its necessary role in textile and medical industries cannot be ignored also. One of the bio-compatible polymers with biodegradability and nontoxicity is Chitosan. Chitin and Chitosan are natural amino poly saccharin, according to the unique structure and highperformance of its multi-dimensional characteristics, it have brilliant and workable usage in various industries, particularly in the medical, textile, surface modifying, tissue engineering, wound healing and drug delivery that have been focused on it mostly during recent years. If mentioned polymer transmits to Nano-phase in range of Nano surface it will cover up the surfaces with very small amounts of the substance. We are facing at pioneer research on the preparation of Chitosan Nanoparticles to enhance the ratio of surface area to volume and increased use of bio-polymer at mentioned industries. To prepare the Nano-chitosan, Chitosan was hydrolyzed in acidic medium molecular weight and particle size by TEM and SEM has been confirmed. Chitosan crystalline particles were analyzed by X-ray diffraction XRD also.
