Assessing bonding and biocompatibility of medical devices

The wetting behaviors of surfaces, such as polymers, hydrogels, and metals, may correlate to their ability to bond to adhesives and to other surfaces, as well as to their biocompatibility.

Dr. Raymond Sanedrin will reveal how medical device developers are using sessile drop measurements to optimize surface treatment and bonding of materials.



In academia and industry, one widely used method to determine how a liquid wets or adheres to a surface is the sessile drop technique. For instance, the hydrophilicity or hydrophobicity of tooth implant materials has been shown to correlate to their degree of contact with their physiological surroundings, and this method can be used to probe such surface property.

The sessile drop method may also provide information on surface free energy — an important parameter for the surface treatment of material used in medical devices. Medical device developers can use this information to optimize surface treatment and bonding of adhesives on surfaces.
