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.

Development and characterization of a stable adhesive bond between a poly(dimethylsiloxane) catheter material and a bacterial biofilm resistant acrylate polymer coating (2017)
Journal Article

Catheter associated urinary tract infections (CA-UTIs) are the most common health related infections world wide, contributing significantly to patient morbidity and mortality and increased health care costs. To reduce the incidence of these infection...

Environmental modification via a quorum sensing molecule influences the social landscape of siderophore production (2017)
Journal Article
Popat, R., Harrison, F., da Silva, A. C., Easton, S. A., McNally, L., Williams, P., & Diggle, S. P. (2017). Environmental modification via a quorum sensing molecule influences the social landscape of siderophore production. Proceedings of the Royal Society B: Biological Sciences, 284(1852), Article 20170200. https://doi.org/10.1098/rspb.2017.0200

Bacteria produce a wide variety of exoproducts that favourably modify their environment and increase their fitness. These are often termed ‘public goods’ because they are costly for individuals to produce and can be exploited by non-producers (‘cheat...

Negative regulation of violacein biosynthesis in Chromobacterium violaceum (2017)
Journal Article
Devescovi, G., Kojic, M., Covaceuszach, S., Cámara, M., Williams, P., Bertani, I., …Venturi, V. (in press). Negative regulation of violacein biosynthesis in Chromobacterium violaceum. Frontiers in Microbiology, 8, Article 349. https://doi.org/10.3389/fmicb.2017.00349

In Chromobacteium violaceum, the purple pigment violacein is under positive regulation by the N-acylhomoserine lactone CviI/R quorum sensing system and negative regulation by an uncharacterized putative repressor. In this study we report that the bio... Read More about Negative regulation of violacein biosynthesis in Chromobacterium violaceum.
