--- title: KRÜSS Webinar | Sticky situations description: 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. If you want to optimize surface treatment and bonding of materials, watch this webinar! --- [![KRÜSS Scientific - Explore the World of Surface Science](https://visit.kruss-scientific.com/hubfs/blue_logo_kruss-01.svg "KRÜSS Scientific - Explore the World of Surface Science")](https://www.kruss-scientific.com/en) ## Focus Webinar # **Sticky situations** #### 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.

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.   ## **What you can expect** - Understand wetting and how it relates to adhesion - Learn how hydrophobicity can indicate biocompatibility - Discover the sessile drop method   ## **Topics** - Which contact-angle measuring technique should be used to observe the wetting behavior of your medical device surface? - How can surface free energy information from contact angles be used to optimize surface treatment of polymer surfaces used for medical devices? - Is the information on the work of adhesion and interfacial tension between substrate and liquid effective in optimizing adhesion? ### **Webinar on demand** If you register now, the recorded version will be available to you immediately.
