Biconically Tapered Fiber Optic Probes for Rapid Label-Free Immunoassays

Biconically Tapered Fiber Optic Probes for Rapid Label-Free Immunoassays

We report use of U-shaped biconically tapered optical fibers (BTOF) as probes for label-free immunoassays. The tapered regions of the sensors were functionalized by immobilization of immunoglobulin-G (Ig-G) and tested for detection of anti-IgG at concentrations of 50 ng/mL to 50 µg/mL. Antibody-anti...
