The fabrication of long-range surface plasmon resonance (LR-SPR) immunosensor from water-stable electrospun polyacrylic acid (PAA) fibers was studied. LR-SPR setup consists of thin gold film and layer of Cytop which let it has larger evanescent field intensity and penetration depth. The water-stable electrospun PAA fibers produced by adding β-cyclodextrin as crosslinker followed by thermal treatment at 180 °C for 40 min were fabricated onto the LR-SPR sensor surface. The free carboxyl group of electrospun PAA fibers was activated to immobilize antibody-antigen in immunosensor application. The layer-by-layer (LbL) system on the electrospun PAA fibers was performed to further increase water-stability of fibers and number of active carboxyl group. Therefore, the LR-SPR immunosensor based on water-stable electrospun PAA fibers was used to detect of human immunoglobulin G (IgG).
