Polymer brushes have many desirable characteristics such as the ability to tether molecules to a substrate or change the properties of a surface. Patterning of polymer films has been an area of great interest due to the broad range of applications including bio-related and medicinal research. Consequently, we have investigated patterning techniques for polymer brushes which allow for two different functionalities on the same surface. This method has been applied to a biosensor device which requires both polymer brushes and a photosensitizer to be polymerized on a patterned gold substrate. Additionally, the nature of patterned polymer brushes as removable thin films was explored. An etching process has enabled us to lift off very thin membranes for further characterization with the potential of using them as Janus membranes for biological applications.
聚合物刷具有许多理想的特性，例如能够将分子 tether 到基底上或改变表面性质。由于包括生物相关和医学研究在内的广泛应用，聚合物薄膜的图案化一直是一个备受关注的领域。因此，我们研究了聚合物刷的图案化技术，该技术允许在同一表面上实现两种不同的功能。此方法已应用于一种生物传感器装置，该装置要求聚合物刷和光敏剂都在图案化的金基底上聚合。此外，还探索了图案化聚合物刷作为可去除薄膜的性质。蚀刻工艺使我们能够剥离非常薄的膜以进行进一步表征，并且有潜力将它们用作生物应用的双面膜。
