| Popis: |
In this work, we present a chemical extrinsic optical fiber sensor, based on a novel micro-pattern of silver nanoparticles, produced by InkJet printing on a polyethylene terephthalate (PET) substrate, covered by a molecularly imprinted polymer (MIP) film. The optical-chemical sensor chip is monitored via two plastic optical fibers (POFs) connected with a light source and a spectrometer. In particular, the pattern is formed by parallel lines arranged in orthogonal position with respect to the direction of the input light. As a proof of concept, we have deposited on the sensor surface an MIP receptor layer specific for furfural (2-FAL). The preliminary experimental results have shown a limit of detection (LOD) relative to 2-FAL equal to 0.05 ppm, demonstrating the goodness and feasibility in biochemical applications of the proposed sensing approach. |
