Histological evaluations were performed on the retina and the optic pathways and included thickness of the different retinal layers, ganglion cells count, and immunohistochemistry for microglial cells, macroglial cells, and oligodendrocytes. The histological results indicate that IAA treatment does not affect the morphology of the inner retina and optic pathways. Electrophysiology confirms the selective rod and partial cone degeneration, but is ambiguous as to the functionality of the optic pathways, seemingly preserved as indicated by the still detectable fVEPs. Overall, the work ameliorates the characterization of such rapid and cost-effective model, providing more strength and reliability for future pre-clinical translational trials. The biopolymer α-chitin is a promising raw source that can be used as a low-cost material for environmental applications. Nevertheless, its low surface properties and high crystallinity limit its use. Recent developments include surface modification as one of the most promising strategies for the application of α-chitin. To this end, we used an acidic treatment, followed by ultrasonication, to modify the α-chitin surface and improve its sorption characteristics to achieve the above goal. Structural analysis and measurement of the physicochemical properties (chemical structure and thermal degradation) of α-chitin, before and after surface modification, indicated no significant changes. However, specific surface area, morphology, surface charge, crystallinity and study of the sorption of methylene blue (MB) from aqueous solution demonstrated surface modification. It was established that the SBET of modified α-chitin increased to 110.7 m2/g and the crystallinity index decreased to 48%. Interestingly, the modified α-chitin could easily adsor
