Molecularly imprinted polymers (MIPs) can be combined with optical fibers (OFs) to create various sensor configurations, yielding low-cost and highly sensitive extrinsic intrinsic sensors. In this work, an MIP-based fiber is obtained by two silica OFs connected via waveguide using MIP as a core of micrometer size (micro OF-MIP-OF sensor). The proposed sensing approach used only receptors implements intensity-based configuration. MIPs present several advantages over bio-receptors exploited realize novel methods. in work specifically designed for 2-furaldehyde (2-FAL) detection, the experimental results demonstrate that micro-probe performs well terms sensitivity selectivity, capabilities applicable application fields. particular, nanomolar detection range, from 1.5 nM 150 nM, has been achieved. Moreover, are comparable or better than those other previously sensors 2-FAL, which employ more complex principles fabrication steps.
