The permanently increasing requirements for products in micro and meso scale lead to a change in the processed materials which have to be adjusted to the respective application. In this paper two different means of material functionalization are presented. On the one hand the materials are functionalized by integration of particles, in the described work nanoparticles, in the polymer matrix. Three different ways for the combination of particles and matrix polymer are demonstrated with the goal to prepare an injectable material. In the second part of this paper functionalization refers to the material properties that are needed for the implementation of the sensor requirements. The objective of the work presented was the development of a biosensor for measurement of cell forces to earn knowledge about vitality and functionality of cells and also for the differentiation of various cell types. For this purpose a flexible and transparent pillar array consisting of 490.000 pillars with a diameter of 5 mu m and a centre to centre distance of 10 mu m was generated by micro injection moulding.
