Personalised precision medicines

Digestion in our intestines includes bile salts, buffer substances, and enzymes. Human aspirates are compared with artificial media that shall mimic human fluids. We study the interaction between drugs and these media, and their influence on drug absorption.

For this purpose, the colloidal particles that are developed, are separated and quantified by a chromatographic method (asymmetric field-flow fractionation, A4F).
