Characterisation of drug delivery systems on skin and investigations of involved mechanisms

Knowledge of drug transport mechanisms from colloidal chemical systems is important for many biomedical applications including drug delivery systems. This platform aims to increase understanding of these mechanisms and reduce the limitations of drug delivery via the topical route.

Our objectives are

  • to design new drug delivery systems such as microemulsions, nanoemulsions, multiple emulsions and liposomes
  • to characterise these systems in terms of NMR, FTIR, DSC, cryoTEM, PCS, etc.
  • to investigate the interactions between formulation-microstructure and model drugs
  • to use in-vitro techniques to understand  the influences controlling skin permeation of model drugs from the developed systems
  • in-vitro/in-vivo correlation of the skin penetration profiles

By employing these insights of the correlation between physico-chemical structure and physiological diffusion processes it will be possible to develop new strategies for dermal application systems. Moreover, the obtained information may also be of great interest for modern anti-age cosmetics.
