Inkjet based 3D Printing of bespoke medical devices that resist bacterial biofilm formation (2020)
Preprint / Working Paper
He, Y., Begines, B., Luckett, J., Dubern, J., Hook, A., Prina, E., …Wildman, R. D. Inkjet based 3D Printing of bespoke medical devices that resist bacterial biofilm formation

We demonstrate the formulation of advanced functional 3D printing inks that prevent the formation of bacterial biofilms in vivo. Starting from polymer libraries, we show that a biofilm resistant object can be 3D printed with the potential for shape a...

Water contact angle is not a good predictor of biological responses to materials (2017)
Journal Article
Alexander, M. R., & Williams, P. (in press). Water contact angle is not a good predictor of biological responses to materials. Biointerphases, 12(2), Article 02C201. https://doi.org/10.1116/1.4989843

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.
