Interaction between (tissue-engineered) implants and the recipient

Build-up and degradation processes at biological interfaces, such as vital implants, can be characterized using non-destructive imaging in vitro as well as ex vivo:

  • Investigation of degradation mechanisms of biodegradable implant materials
  • Visualization and quantification of processes of tissue formation
  • Identification of foreign body reactions and fibrotic changes
  • Prediction of potential immune response by in situ phenotyping of immune cells (e.g. macrophages)

Evaluation

  • Visual documentation

  • Mass, molecular weight

  • Mechanical properties (based on ISO 25539), rheology

  • Release kinetics of active substances

  • Detection of degradation products (based on DIN EN ISO 10993-13 and -15)

Other services

  • Development of product-specific test plans according to relevant standards
