TL;DR: It has been shown that the system is capable of providing positive response to the bacterial concentration in less than 10 min, demonstrating good possibilities to be commercially developed as a portable field sensor.

TL;DR: The authors analyze the characteristics of an immunosensor based on the evanescent field in plastic optical fibers with macro curvature by comparing experimental with simulated results, and proposes new geometric configurations of biosensors that can be easily constructed and that promise improved sensitivity.

TL;DR: In this article, a 1-mm diameter plastic optical fiber (POF) was used to detect sulfate-reducing bacteria (SRB) in production water in about 30min for concentrations of 104, 106 and 108MPN/mL.

TL;DR: The authors characterize four U-shaped plastic optical fiber sensors, manufactured with a particularly developed simple mechanical scheme, which are characterized and implemented as refractometry sensors, which lead to the evaluation of the sensitivity, accuracy and repeatability.

TL;DR: The authors investigated and characterized different shapes of plastic optical fiber sensors, U-shaped with two different radiuses, coil-shaped and meander-shaped, implemented as refractometry sensors, which detected concentrations of bacterium Escherichia coli in water.
