WebSep 24, 2024 · Abstract. Chitosan has garnered much interest due to its properties and possible applications. Every year the number of publications and patents based on this polymer increase. Chitosan exhibits poor solubility in neutral and basic media, limiting its use in such conditions. Another serious obstacle is directly related to its natural origin. Webchitosan is pH dependent allowing processability under mild conditions [20]. Chitosan with protonated amino groups becomes a polycation that can subsequently form ionic complexes with a wide variety of natural or synthetic anionic species [20], such as lipids, proteins, DNA and some negatively charged synthetic polymers as poly (acrylic acid ...
