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.

Small interferring RNAs (siRNAs) can inactivate viruses by so-called gene silencing. In order to use this process in biomedicine, the transport of unstable siRNAs must be improved. In the presented study, siRNAs are coupled to chitosan microparticles and investigated for the inactivation of viral proteins in HIV-1 infected C8166 cells. siRNA transfection mediated by chitosan microparticles for the treatment of HIV-1 infections of human cell lines
