Diblock Copolymer Patterned Surfaces for Ulva Zoospores Settlement Assays

摘要

Biofouling of surfaces submerged in a marine environment can be prevented by using coatings that have antifouling properties and/or foul-release properties.1 These coating must also be free of biocides due to recent regulations. Studies have shown that zoospores of the fouling macroalga Ulva are affected by surface properties such as chemistry2 and topography3. In particular,micron-sized topographies were fabricated in polydimethylsiloxane by Schumacher et al. Ulva zoospore settlement was influenced by the design and length-scale of the patterns.3 The effect of both nanoscale topographic features and local chemistry variation has not been investigated.
