AFM for Biomaterials Research

Coronary stent surface imaged using atomic force microscopy

Atomic force microscopy allows researchers to characterize the topography and mechanical properties of biomaterials. The AFM can accurately measure surface roughness and microstructure as a function of composition and processing variables. Biomaterials can also be inspected after in vitro testing or after explantation to assess changes in surface features. A wide range of AFM techniques can be applied to measure the stiffness, moduli, and dissipation of biomaterials.

  • Measure surface morphology / surface roughness
  • Measure material properties (elastic modulus, loss modulus, hardness)
  • Measure surface changes during or after exposure to liquids (e.g. as related to biocompatibility)
  • Implants
  • Drug coatings (stents, catheters, etc.)
  • Anti-fouling coatings (catheters, implants, biosensors, etc.)
  • Biomineralization studies
  • Tissue engineering and scaffold engineering
