\nabstract: Over the years plasma has played a crucia
 l role in surface modification processes\, such as sputtering\, activation
  or deposition of various materials. As the plasma-surface interactions ar
 e very complex\, there is a lack of scientific understanding in this topic
 . This problem became even more pronounced in recent years\, as it became 
 feasible to generate plasma in the laboratory frame\, which does not induc
 e thermal damage on heat sensitive materials like paper\, polymers\, texti
 les or even living tissue. As these materials are mostly consisting of lar
 ge\, complex organic molecules\, the study of the plasma-surface interacti
 on is highly challenging. Most of the underlying chemical and physical pro
 cesses are barely or not at all understood. Thus\, it is vital to enhance 
 the basic knowledge about the interaction between different types of plasm
 a and organic materials to optimise industrial and medical plasma-based pr
 ocesses. However\, the experimental access to these problems is very chall
 enging\, especially when it comes to biomedical samples were the complexit
 y is even larger as one has to investigate mostly living cells or cell sys
 tems. The aim of this talk is to outline how the scientific understanding 
 of plasma interaction with industrially and medically relevant materials c
 an be enhanced by studying the effects of plasma interaction with biomolec
 ules.
