Abstract: In order to enable local functionalization of label-free optical waveguide biosensors in a cost effective mass-fabrication compatible manner, we investigate surface modification employing inkjet printing of a) functional polymers (biotin-modified polyethylenimine (PEIB)) to implement high receptor densities at the surface and b) UV-curable benzophenone dextran (benzo-dextran) to form a voluminous porous hydrogel matrix. The combination of these approaches on a single chip is promising for the detection of biomolecules. We evaluate these functional polymers and hydrogels on an integrated four-channel silicon nitride (Si3N4) waveguide based Mach-Zehnder interferometric (MZI) sensor platform operating at a wavelength of 850nm (TM-mode).Summary: In order to enable local functionalization of label-free optical waveguide biosensors in a cost effective mass-fabrication compatible manner, we investigate surface modification employing inkjet printing of functional polymers and UV-curable benzophenone dextran.References: [1] K.
