“…The percentage of recovery for each water sample is calculated using the relation given below. (5) Table 2 presents that the percentage recovery of the proposed sensor lies between (93 ± 4.5) % to (105 ± 4) %, which confirms the significant working potential of the proposed sensor in real sample analysis. However, in Table 2, the measured p-cresol concentrations of the real water samples is slightly different from the actual value and, in some cases, it is greater than the actual one.…”

“…Among them, the most commonly produced toxic, harmful phenolic compound is 4-methyl phenol, also known as p-cresol (para-cresol). 5 The extreme application and massive production of p-cresol make this one of the leading health risks. It is extensively used in agrochemical industries for making different pesticides and herbicides.…”

“…Water pollution endangers human health and welfare, impeding the sustainable development of the economy. − Different phenolic compounds produced through the decomposition of organic materials, burning fossil fuels, or effluents of industrial wastage are one of the major sources of water pollution. Among them, the most commonly produced toxic, harmful phenolic compound is 4-methyl phenol, also known as p -cresol ( para -cresol) . The extreme application and massive production of p -cresol make this one of the leading health risks.…”

Selective detection of toxic pollutants present in water has been a severe challenge to the scientific community for a long time. The noble integration of optical fiber-based interferometry with a bio-recognizing element molecular imprinting polymer (MIP) exhibits a promising technique for selective and susceptible biochemical detection. Here, we report a compact, stable, reproducible, and label-free optical sensor using a combined approach of photonic crystal fiber (PCF)-based modal interferometry and MIP nanoparticles (MIP-NPs) for selective detection of water pollutant p-cresol with an extremely low limit of detection (LOD). The MIP-NPs having a greater surface-to-volume aspect ratio allows more target analytes to bind. The sensor immobilized with MIP-NPs shows unprecedented sensitivity of 1.865 × 108 nm/M with specific and repeatable detection performance for a broad dynamic detection range of 10–8–10–3 M. The sensor offers a remarkable detection ability of as low as 1.55 nM concentrations of p-cresol in the aqueous medium, for water quality monitoring. Fast response, high resolution, compact size, label-free broad detection range, and selective reusable performance of the proposed sensor exhibit potential for board practical utilizations, including medical sectors, online and remote biosensing, and water resource monitoring.
