This manuscript explores the use of nanostructured chitosan for intranasal drug delivery, targeting improved therapeutic outcomes in neurodegenerative diseases, psychiatric care, pain management, vaccination, and diabetes treatment. Chitosan nanoparticles are shown to enhance brain delivery, improve bioavailability, and minimize systemic side effects by facilitating drug transport across the blood-brain barrier. Despite substantial advancements in targeted delivery and vaccine efficacy, challenges remain in scalability, regulatory approval, and transitioning from preclinical studies to clinical applications. The future of chitosan-based nanomedicines hinges on advancing clinical trials, fostering interdisciplinary collaboration, and innovating in nanoparticle design to overcome these hurdles and realize their therapeutic potential.

Food packaging industries are growing to meet consumer demand and prevent pollution by adopting significant biopolymer advancements. Therefore, this study aimed to develop functionally active chitosan (CS)/polyvinyl alcohol (PVA)-based biopolymer films and evaluate the effect of Justicia Adhatoda extract (JAE), pure quercetin (Q), and CS-capped quercetin nanoparticles ((Q) NPs) on sustainable bread packaging. CS was successfully loaded onto (Q) by the one-pot method, which was confirmed by light absorption spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD).

Gastric ulcer (GU), a common digestive system disorder in clinical practice, often arises from excessive alcohol consumption and other factors that irritate the gastric mucosa. Effective treatment of GU remains challenging due to the poor targeting, limited efficacy, and significant side effects associated with current therapeutic approaches. To address these limitations, we developed a microenvironment-responsive hydrogel composed of sodium alginate (SA) and chitosan (CS), incorporating MnO nanoparticles and pachymic acid (PA).

Nickel pollution adversely affects human health and causes various disorders, mainly hepatic and renal dysfunction. The present work focused on a comparative evaluation of the pure form of curcumin (CU) with curcumin-encapsulated chitosan nanoconjugates (CS/CU NCs), on mitigation of the delirious effects of Ni on hepatorenal tissue. Forty-two male rats were allocated into 6 groups (n = 7 for each) as follows: (1) control, (2) CU, (3) CS/CU NCs, (4) Ni, (5) Ni + CU, (6) Ni + CS/CU NCs.
