Modification of chitosan changes the original properties of chitosan so that it can be more suitable for adsorption of fluoride ions.
The DD plays a key role in cell adhesion and proliferation but does not change the cytocompatibility of chitosan.
Additionally, the microenvironment and the secondary structure of BSA were changed with the addition of chitosan, and chitosan was found to quench the intrinsic fluorescence of BSA.
The results showed that the heparin immobilization and NGF loading did not cause the change of bulk properties of chitosan scaffolds except for morphology and wettability.
The existence of chitosan layer changes the properties of magnetite nanoparticles and makes it water soluble and biocompatible, which makes it has potential applications in the field of biotechnology as magnetic resonance imaging contrast agents and drug carrier.
Apart from retarding moisture migration and the loss of volatile compounds, reducing the respiration rate, and delaying changes in textural properties, another advantage of chitosan films is that it is biodegradable.
Further electrochemical results showed that the addition of chitosan did not change the anodic and cathodic behavior of the films, but enhanced the corrosion resistance by reducing the corrosive ability SRB medium, inhibiting bacteria attachment and raising the films' electric conductibility to a certain extent.
In contrast, no significant change (p > 0.05) in viscosity of chitosan as well as the S-protected thiomers could be detected after this period.
For each application, different properties of chitosan are required, which changes with the degree of acetylation and molecular weight.
This study indicates that surface modification by argon plasma leads to changes in filtration characteristics and ionic permeability of chitosan membranes.
