Special Issue Information

Dear Colleagues,

In recent years, fiber optic chemical sensors and biosensors integrated with functional materials have attracted significant attention due to high sensitivity, excellent stability, good specificity, and cheap analytical cost. Various functional sensing materials are available for fiber-optic chemical sensors and biosensors, such as graphene, metals and metal oxides, carbon nanotubes, nanowires, nanoparticles, quantum dots, etc. Nowadays, fiber optic chemical sensors and biosensors have great potential in a broad range of applications, including pH, humidity, gases, ions, glucose, DNA, and some other bioactive species measurement.

This Special Issue, entitled “Recent Advances and Tendencies on High Sensitive Fiber Optic Chemical Sensors and Biosensors”, welcomes contributions of original research or comprehensive review submissions reporting the latest research progress and development on high sensitive fiber optic based sensing methods and technologies.

In this study, a surface plasmon resonance (SPR) sensor based on modified plastic optical fibers (POFs) was combined with a specific molecularly imprinted polymer (MIP), used as a synthetic receptor, for glyphosate (GLY) determination in aqueous solutions. Since GLY is a non-selective herbicide associated with severe environmental and health problems, detecting glyphosate in environmental and biological samples remains challenging. The selective interaction between the MIP layer and GLY is monitored by exploiting the SPR phenomenon at the POF’s gold surface. Experimental results show that in about ten minutes and by dropping microliter volume samples, the presented optical–chemical sensor can quantify up to three orders of magnitude of GLY concentrations, from nanomolar to micromolar, due to a thin MIP layer over the SPR surface. The developed optical–chemical sensor presents a detection limit of about 1 nM and can be used for onsite GLY measurements. Moreover, the experimental analysis demonstrated the high selectivity of the proposed POF-based chemical sensor. Full article
