Introduction of multiple functionalities via polymerization of doped bis-SorbPC. A) Poly(biotin lipid/bis-SorbPC) with DOPC fused into the void regions. B) Poly(bis-SorbPC) patterned capillary with 10% biotin lipid/90% DOPC lipid fused into the void regions. For A) and B), patterns were developed via consecutive introduction of streptavidin, biotin-anti-6xHis, and 6xHis-EGFP. C) Poly(Rh-DPPE/bis-SorbPC) (red) with NBD-DOPE-doped DOPC fused into void regions (green). D) Poly(biotin-DHPE/bis-SorbPC) with NTA-doped DOPC fused into the void regions. Streptavidin-fluorecein conjugate and 6xHis-DsRed are introduced into the capillary to develop the regions containing biotin (green) and Ni2+-NTA (red). E) Poly(Rh-DPPE/bis-SorbPC) (red) and poly(NBD-DOPE/bis-SorbPC) (green). F) Poly(Rh-DPPE/bis-SorbPC) (red), poly(NBD-DOPE/bis-SorbPC) (green), and NTA-Ni-6xHis-Cerulean (blue). All capillaries are 50 μm i.d.
