A phenylboronic-acid-derivatized poly (acrylic acid) (PAA-PBA)/poly(vinyl alcohol) (PVA) functionalized thin-core fiber (TCF) optical sensor is proposed for glucose detection. The unique Michelson-type fiber interferometer sensor was fabricated by splicing a short segment of TCF with a single-mode f...
