SUMMARY:Colloquium - Bio-Inspired Surface Engineering: From New Anti-Infection  Strategies to Low-Cost Water Monitoring
DESCRIPTION:Over millions of years\, Nature has developed a variety of highly effective\, sustainable solutions to a\nwide range of problems. Relatively recent advances in materials science are now making it possible\nfor scientists and engineers to adapt similar strategies for human problems. In this seminar\, I will\npresent our recent work on two such efforts: (1) exploring new ways of creating infection-resistant\nmaterials for healthcare that remove the need for antibiotics and (2) leveraging industrial\nmass-manufacturing capacity to create large-scale surfaces with functionality such as sensing. In\nour work on infection-resistant materials\, we draw from the way that Nature uses liquid-like layers\nas one effective method to control microorganisms. We created a similar system for commercially\navailable urinary catheters\, one of the most widely used and infection-prone medical devices. Tests\nof the modified catheter materials both in vitro and in vivo demonstrated that the presence of a\nliquid-like surface effectively prevented the attachment and spread of six of the most common\npathogens in catheter-associated urinary tract infection. The materials also resisted colonization by\nan emerging fungal pathogen of concern\, Candidozyma auris. In our work on functional surfaces\, we\nrepurpose a butterfly-scale-inspired nanoscale surface textured produced at 4\,000m\n2/h for the fashion industry as a water-quality sensor. By continuously monitoring the diffraction pattern\nproduced by the surface texture as water passes over it\, we show that it is possible to detect and\nquantify a variety of model contaminants including chemical compounds\, sediment\, and algae.\nPreliminary field testing in estuaries\, rivers\, and lakes around Maine confirmed the potential of\nbio-inspired diffraction sensing for low-cost environmental monitoring. Together\, these projects\nprovide a glimpse of the range of solutions that can be generated by looking to Nature for inspiration.
