Proteinaceous secretions are significant contributors to marine biofouling. The resulting interfacial films can be physisorbed or chemisorbed, and have varying degrees of permanency � they may be highly polymerized and cross-linked, or simply sticky enough to allow surface exploration. In this talk, I will present examples of how we have applied a broad suite of in situ microscopy and spectroscopy approaches to reveal how barnacles form and cure their adhesive, as well as its properties and composition. Our in situ approaches include performing temporally- and spatially-resolved microscopy and spectroscopy through adhesive interfaces transparent at UV, visible, IR, and x-ray wavelengths. We have used these and other materials science tools to extend our understanding of the properties and development of barnacle adhesive interfaces. Barnacle adhesion is promoted by both chemistry and structure at multiple scales. Ultimately, we aim to use this information to develop better antifouling strategies that reduce bioadhesive strength.
