Chitosan is a natural biopolymer derived from deacetylation of chitin and it has been investigated with interdisciplinary approaches for multitude applications. Chitosan biomaterials possess unique properties such as biocompatibility, biodegradability, non-toxicity, muco-adhesion and a wide range of antibacterial and antifungal activity. Additionally, chitosan is the only cationic polysaccharide in nature and can be chemically modified to derivatives, based on the aim of function and application. The distinctive properties of chitosan and its derivatives have aroused interest in pharmaceutical industries and biomedical fields worldwide. This review discusses the crucial role of chitosan in production of bio-dental materials and accentuates its current profitable utilizations in oral drug delivery system, bone tissue engineering for treatment of periodontitis and dentin-pulp regeneration. Chemical modifications and incorporation of diverse bioactive molecules in order to improve the mechanical and biological characteristics of chitosan have also been discussed.

Background: In this study, we prepared a porous gradient scaffold with hydroxyapatite microtubules (HAMT) and chitosan (CHS) and investigated osteogenesis induced by these scaffolds.
Methods: The arrangement of wax balls in the mold can control the size and distribution of the pores of the scaffold, and form an interconnected gradient pore structure. The scaffolds were systematically evaluated and for biocompatibility, biological activity, and regulatory mechanisms.
The Efficiency of Chitosan Against Tert Butylhydroquinone (TBHQ)-Induced Neurobehavioral Changes and Toxicity Effects in Male Rats.

Background: We investigated chitosan's protective effects against tertiary butylhydroquinone (TBHQ)-induced toxicity in adult male rats, focusing on cognitive functions and oxidative stress in the brain, liver, and kidneys.
Methods: Rats were divided into four groups (n = 8/group): (1) Control, (2) Chitosan only, (3) TBHQ only, and (4) Chitosan + TBHQ.
Results: TBHQ exposure led to significant cognitive impairments and increased oxidative stress, marked by elevated malondialdehyde (MDA) and decreased superoxide dismutase (SOD) and glutathione (GSH) levels.

This study presents the fabrication of a sustainable flexible humidity sensor utilizing chitosan derived from mealworm biomass as the primary sensing material. The chitosan-based humidity sensor was fabricated by casting chitosan and polyvinyl alcohol (PVA) films with interdigitated copper electrodes, forming a laminate composite suitable for real-time, resistive-type humidity detection. Comprehensive characterization of the chitosan film was performed using Fourier-transform infrared (FTIR) spectroscopy, contact angle measurements, and tensile testing, which confirmed its chemical structure, wettability, and mechanical stability.

Effluents containing synthetic anionic dyes can pose a risk to ecosystems, and they must be treated before their release to the environment. Biosorption, a simple and effective process, may be a promising solution for treating these effluents. In this work, chitosan beads were crosslinked with epichlorohydrin to produce a highly stable and performant biosorbent to remove Brilliant Blue FCF dye.
