Microfluidics as a platform technology for the production of chitosan nanoparticles

The preparation of chitosan-based nanoparticles by ionotrophic gelation often leads to high batch-to-batch variability as well as in low reproducibility. A possible solution to this could be controlled mixing on a microfluidic scale. In the study presented here, chitosan tripolyphosphate nanoparticles with siRNA, mRNA and β-galactosidase as cargo will be prepared using microfluidics.

Chitosan microparticles for the treatment of HIV-1 infection

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
