NANOPARTICLES COMPRISING CHITOSAN AND CYCLODEXTRIN

摘要

The invention relates to a system comprising nanoparticles for the release of biologically-active molecules, in which the nanoparticles contain: (a) at least 40 wt.- % chitosan or a derivative thereof, and (b) less than 60 wt.- % cyclodextrin or a derivative of same, whereby both components (a and b) are mixed without a covalent bond forming therebetween. The inventive system enables the effective association of biologically-active molecules and the subsequent release thereof in a suitable biological environment.
