How surface roughness and wettability affects biocompatibility

Posted by Anna Oom on November 24, 2015


Various types of artificial materials are being utilized as implants in all fields of medicine. The surface properties of the implant determine its interactions with the surrounding host tissue. Physicochemical properties of the surface, like wettability and surface roughness, are of prime importance for the optimization of adhesion, spreading and proliferation of cells.

Building an Appetite for Hydroxyapatite Q-Sensors

Posted by Olivia Uddenberg on October 6, 2015

Hydroxyapatite in biomaterial and medical device research

Within biomaterials research and development, hydroxyapatite (HA) is well known for its biocompatible properties, particularly in bone bonding, and for its potency of rapid integration into the human body. Orthopaedic and dental devices are often coated with hydroxyapatite to facilitate integration and acceptance by human tissue.

Top 5 Q-Sensors for biomaterials & medical device research

Posted by Anna Oom on September 11, 2015

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.

Interview with Prof. Joy on his biomaterials research - Part 2

Posted by Anna Oom on August 31, 2015

Abraham Joy is an Assistant Professor at the Department of Polymer Science at the University of Akron, USA. Recently we had the opportunity to interview him about his research within biomedical applications. There was so much interesting in the interview that we had to divide it into two parts. Here comes the second part!

Interview with Prof. Joy on his biomaterials research - Part 1

Posted by Anna Oom on August 24, 2015

Abraham Joy is an Assistant Professor in the Department of Polymer Science at the University of Akron, USA. Recently we had the opportunity to interview him about his research within biomaterials- and biomedical applications.

 

Professor Joy has a Ph.D. in Organic Chemistry from Tulane University. He carried out postdoctoral work in the area of bioorganic chemistry at Georgia Tech. Subsequently he did a second postdoc at the New Jersey Center of Biomaterials, and that’s where he started working with polymers and specifically within biomaterials applications which lead him to his position at Akron. Now let’s get to the interview:

Protein Adsorption to Biomaterials

Posted by Gunilla Rydén on July 14, 2015

Blood-material interactions are critical for the performance and biocompatibility of implantable medical devices used in thousands of patients everyday. When a biomaterial is introduced into the body, protein adsorption and activation of complement proteins occur. Complement proteins are mediators of inflammation, and are therefore of interest in biomaterials research. Success often depend on interactions between the biomaterial’s surface and its physiological environment. Modifications are often made to the surface of biomaterials to modulate their physical and chemical properties in order to improve the functionality of the biomaterial in a given application.
