Description

Full text: We present a new drug carrier system that consists of silica hybrid gels having organic side groups. A major difference to existing formulations is that the matrix is generated in the presence of the drug molecule in a self-assembling process. The critical role of pore architecture (size and accessibility) in the tailored drug release is clearly revealed by positron annihilation lifetime spectroscopy (PALS), while the classical nitrogen adsorption technique (BET method) is not suitable here to indicate the internal void structure.
