“…High hydrodynamic diameter values obtained from DLS are the result of the particle aggregation. A similar phenomenon was reported by Taghizadeh & Bahadori (Taghizadeh & Bahadori, 2013). They claimed that the hydrodynamic diameter depends on degree of substitution and deacetylation degree of CHS since CHS NPs are prepared by the ionic crosslinking between positive charged ammonium ions of CHS and negative ions of STPP.…”

In this study, allantoin-loaded chitosan nanoparticles were prepared and the effect of molecular weights (low, medium, and high) of chitosan was investigated on the release of allantoin. The allantoin-loaded chitosan nanoparticles were characterized by various methods. The morphology, size, zeta potential, and loading efficiency were affected by the molecular weight of chitosan. The results displayed that the average hydrodynamic diameter of chitosan nanoparticles was in the range of 427-768 nm and the zeta potential values from 5.97 to 5.12 mV was obtained. The allantoin release from chitosan nanoparticles reached the plateau level in 96 hours. Cumulative allantoin release values of low, medium, and high molecular mass chitosan nanoparticles were determined as 43%, 30%, and 27%, respectively. According to the results, the molecular weight of chitosan influenced on allantoin release.

“…The spatial hindrance and hydrophobic forces in the aromatic substituent groups of chitosan derivatives have important roles in the crystallinity and thermal stability of the final products [ 103 ]. Aromatic chitosan derivatives, such as chitosan tripolyphosphate nanoparticles, exhibit some attractive properties, such as delivery of macromolecules in muscles, having pharmaceutical and medical applications [ 104 ].…”

“…The results showed that for the strong binding of chitosan to the surface of cell membranes, which automatically involves the improvement of its mechanical properties, the presence of functional groups such as amino and phenolic hydroxyl ones is sufficient. The same studies showed that the presence of these groups onto chitosan determines an improved tensile strength [ 102 , 104 ].…”

The biomedical and therapeutic importance of chitosan and chitosan derivatives is the subject of interdisciplinary research. In this analysis, we intended to consolidate some of the recent discoveries regarding the potential of chitosan and its derivatives to be used for biomedical and other purposes. Why chitosan? Because chitosan is a natural biopolymer that can be obtained from one of the most abundant polysaccharides in nature, which is chitin. Compared to other biopolymers, chitosan presents some advantages, such as accessibility, biocompatibility, biodegradability, and no toxicity, expressing significant antibacterial potential. In addition, through chemical processes, a high number of chitosan derivatives can be obtained with many possibilities for use. The presence of several types of functional groups in the structure of the polymer and the fact that it has cationic properties are determinant for the increased reactive properties of chitosan. We analyzed the intrinsic properties of chitosan in relation to its source: the molecular mass, the degree of deacetylation, and polymerization. We also studied the most important extrinsic factors responsible for different properties of chitosan, such as the type of bacteria on which chitosan is active. In addition, some chitosan derivatives obtained by functionalization and some complexes formed by chitosan with various metallic ions were studied. The present research can be extended in order to analyze many other factors than those mentioned. Further in this paper were discussed the most important factors that influence the antibacterial effect of chitosan and its derivatives. The aim was to demonstrate that the bactericidal effect of chitosan depends on a number of very complex factors, their knowledge being essential to explain the role of each of them for the bactericidal activity of this biopolymer.
