| Abstract | ||||
| Chitosan is the second most abundant natural polysaccharide after cellulose, which is the most widely used and distributed biological material. Chitosan is derived from chitin, which is a structural component of the external structures of crustaceans such as shrimp and crab, and it can be used to create nanoparticles in a number of ways. The formation of his excellent film properties can be used to create movies, fiber and water gels containing water / nano particles min. The goal of this study was to easily and cheaply extract and characterize nanochitosan from marine crustaceans, as well as to develop nanochitosan membranes. Chemical-mechanical method, acid hydrolysis, sonication and filtration were used, where nano-chitosan membranes are obtained by casting and evaporation. Techniques used for characterization included Transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), Scanning electron microscopy (FEI-SEM). The results of characterization of nanochitosan formation using infrared absorption spectra showed several peaks showing functional groups of chitosan. SEM micrographs showed roughly spherical NC nanoparticles with nanochitosan particle diameters ranging from 22.1 to 51.6 nm. Image TEM showed spherical shaped chitosan nanoparticles with diameters ranging from 21 nm to 34 nm were obtained. Chitosan was obtained as a white powder and was highly soluble in 1% acetic acid using the procedure developed in this study. The findings point to the development of distinct films with high transparency, strength, and durability suitable for pharmaceutical and medical applications. | ||||
