Good dentures are becoming increasingly important as the population ages. Conventional materials for the base of dentures are often porous and thus susceptible to deformation or microbial colonization. To prevent this, chitosan is added to polymethyl methacrylate resin in the presented study.

The antiviral properties of chitosans, in contrast to chitosan derivatives, have been little considered. For this reason, the study presented here investigated the antiviral activity of three chitosans against the SARS-CoV-2 surrogate, bacteriophage phi6.

Hydrogels can have versatile applications in biomedicine by forming a 3D network. In the study presented here, an antibacterial, adhesive, self-repairing hydrogel was prepared from carboxymethylchitosan (CMC) and oligomeric polycyanidin (OPC) and the influence of OPC content was investigated.

Glioblastomas are difficult to treat due to the blood-brain barrier and drug resistance. To improve the efficacy of treating glioblastomas with selenium nanoparticles (Se-NPs), Se-NPs were coated with chitosan in the presented study.
