“…However, its potential utilization could certainly be much larger, including for example tissue engineering, drug delivery, wound dressing, scaffolds, pharmaceutical contaminant removal, cancer diagnosis, composites and nanocomposites, high-tech materials, packaging, dye removal. In nanocomposite material preparation, chitosan has been demonstrated to be successful as a stabilizing agent, for example, for titania nanoparticle dispersion [ 115 ], expanded graphite [ 116 ], graphene oxide [ 117 , 118 ] and rare-earth elements [ 119 ]. In addition, both chitin and chitosan can be mixed with other biopolymers, such as poly (vinyl alcohol), alginate, collagen, cellulose acetate, by obtaining bio-polymer blends, characterized by improved mechanical properties [ 120 , 121 , 122 , 123 ].…”
