|a The utilization of photopolymerized phospholipids for the preparation of spatially defined, chemically functionalized, micron-sized domains within enclosed fluidic channels was recently reported (Ross, E. E.; et al. J. Am. Chem. Soc. 2005, 127, 16756-7). Fabrication of the phospholipid patterns is achieved via self-assembly of photoreactive phospholipid membranes that are subsequently cross-linked via UV-irradiation through a photomask. In this work, we have characterized the chemical and physical stability of the self-assembled, chemically functionalized, cross-linked phospholipid patterns and extended this approach to the preparation of cross-linked phospholipid patterns with multiple chemical functionalities. Poly(bis-SorbPC) patterns were found to withstand a number of chemical and physical challenges, including drying/rehydration, solvent or surfactant rinse, and extended storage without compromising the size or morphology of the cross-linked phospholipid patterns. Nonspecific adsorption of proteins was found to be markedly reduced in the presence of UV-photopolymerized poly(bis-SorbPC) compared to bare silica capillaries. The resulting barcode-like patterns were used to prepare protein-functionalized domains via covalent attachment of fluorescent proteins and active enzymes to chemically functionalized lipid headgroups. We also demonstrate multiple component polymer lipid patterns with adjacent chemically functionalized polymer lipid regions. The unique combination of stability, biocompatibility, reduced nonspecific protein adsorption, and the availability of numerous chemically functionalized lipid headgroups suggests the utility of this approach for preparing a widely applicable platform for multicomponent, high-throughput chemical sensing and screening applications
