Biomaterials & medical device research - Top 5 Sensors

The QCM-D technology is used for research in many biomaterial- and medical device applications. Since the sensor is a critical part of the measurement, and the coating of the sensor is even more important in order to get the desired interactions, we wanted to give you some inspiration to a number of our sensor coatings suitable for biomaterial- and medical device research.

  1. Hydroxyapatite – What can be more useful than a sensor that has the same chemistry as bone and teeth? The hydroxyapatite sensor has a hydroxyapatite coating on top of a TiO2 coated QCM-D sensor. It is commonly used for biomolecule-surface interactions in biomaterials and medical device research.
  2. Titanium – A classic material for medical implants thanks to its biocompatibility and mechanical properties. As it is often used for long-term implants, studies of how the material interacts with the bio-environment over time is of interest.
  3. PMMA – Polymeric materials are rapidly replacing other materials for use as biomaterials because of their versatility. Polymethylmethacrylate (PMMA) is used extensively as bone cement and is also used for replacement of intraocular lenses.
  4. Stainless steel – Stainless steel is widely utilized in both orthopedic and cardiovascular implants. Having a stainless steel coated sensor enables studies of hemocompatibility and biomineralization relevant for stents and fracture fixation devices to name a couple.
  5. PTFE – Another polymer, commonly used for vascular grafts, catheter coating and soft tissue augmentation. The PTFE (polytetrafluoroethylene) we have is Amorphous Fluoropolymer AF1600.

A top 5 list doesn’t really give room for all the sensors coatings relevant to biomaterials research. Here you can read the full list of sensors for more inspiration!
