Water contact angle is not a good predictor of biological responses to materials (2017)
Journal Article

Often the view is expressed that water contact angle (WCA) or other wettability/surface energy measurements made on a material surface can be used to predict cellular attachment to materials, e.g., bacteria attach to hydrophobic surfaces. In this art... Read More about Water contact angle is not a good predictor of biological responses to materials.
