In the field of biomedicine and material sciences, we offer a wide range of testing services for medical implants.

Those are:

Material characterization

• Topography: characteristic structures, defects
  • SEM, white light confocal microscopy, AFM
• Coating analysis: Thickness, cross-section, coating sequence
  • FIB, SEM, TEM, ellipsometry
• Active ingredient distribution on surfaces
  • Raman
• Chemical characterization (based on ISO 10993-18): Influence of production, storage, degradation, etc.
• XPS, FTIR, Raman, SNMS
• Surface wettability

Evaluation of coating processes

• Analysis of structure and thickness of layer
• Testing of surface wettability and topography
• Testing of degradation kinetics and degradation products based on ISO 10993-13, ISO 10993-15
• Analytics for drug release

Mechanical checks

• Static material and component tests (tension, compression, bending, shear, peel)

Corrosion tests

• Corrosion resistance (based on ISO 10993-15 and ASTM F 2129)
• Degradation products from metals and alloys (based on DIN EN ISO 10993-15)
• Surface analysis (light, scanning electron microscopy)

Degradation investigations

• Release/degradation (mechanism and kinetics) of thin polymer layers based on DIN ISO standard 10993
• Detection of degradation products: qualitative and quantitative (based on ISO 10993-13, -15, ISO 13781; e.g. polarography)
• Degradation kinetics (sample and fragments)

Testing for cleanliness

• Comparison with standard surfaces
• Filmic contamination and particles
