In this article, the relationship between the properties of different membranes (agar, chitosan, and agar + chitosan) and biodegradability in natural and sterilized soil was investigated. The membranes under investigation exhibited variations in the biodegradation process, a phenomenon closely linked to both the soil microbiota composition and their water affinity. Higher solubility in water and greater swelling tendencies correlated with shorter initiation times for the biodegradation process in soil. Overall, all tested membranes began biodegradation within 14 days, as assessed through thickness and morphological analysis parameters, demonstrating a superior degradation rate compared to low-density polyethylene films.

. Larvae of the insect can represent an alternative source for low-molecular-weight chitosan (CS) production compared with CS from crustaceans (CS), making it appealing in terms of pharmaceutical applications. Hence, the performances of CS and CS were compared herein by investigating the in vitro features of nanoparticles (NPs) made from each polysaccharide and administered with the antioxidant quercetin (QUE).

To develop a sustained transdermal drug delivery system for gout treatment, double-layered patches containing allopurinol (ALP) were prepared using starch, chitosan, polyvinyl alcohol, and plasticizers. The chitosan-based first layer was designed to modulate the ALP release from the starch-based second layer, enabling sustained drug delivery for continuous therapeutic effect. The physicochemical properties of ALP and the prepared patches were characterized by physical properties, FE-SEM, FT-IR, H NMR and C NMR.

Objective: Wound healing is a topic of significant interest in current times due to the rising prevalence of chronic illnesses linked to poor healing. The purpose of this work was to develop a guar gum (GG) & chitosan (CS) composite metoprolol succinate-loaded novel scaffold by the lyophilization technique and subsequently evaluate for several characteristics necessary for surgical wound healing.
Methods: The interaction of GG and chitosan was evaluated by Fourier transform infrared spectroscopy (FTIR) and thermal analysis (DSC, TGA).
