Keywords:Femtosecond laser ablation, Antibody immobilization, Laser-induced hydrophilic structure

We successfully demonstrate localized immobilization of anti-adiponectin antibodies on superhydrophilic micro-grooved structures in a PMMA (poly methyl methacrylate) capillary flow immunoassay microchip. The microstructures were generated using femtosecond laser machining.
