FIG. 1.

Schematic of the fabrication process; (a) coiling a tapered fiber onto an expendable PMMA rod connecting Teflon tubes, (b) covering the coil with a Teflon solution, and (c) after removing of the PMMA rod by dipping the device in acetone for one day, the analyte may freely move in the channel.

FIG. 3.

Comparison between absorption spectra of Brilliant Blue FCF aqueous solution measured with the proposed device (, solid black line) and reference spectrum recorded with a spectrophotometer (, red dashed line).

FIG. 5.

Dependence of the measured optical losses at 630 mn on the analyte molar concentration. Dashed blue line represents the fitting curve calculated by the Gupta model of EW absorption in optical fibers. Solid red line represents the fitting result assuming adsorption mechanism and applying the Langmuir equation.
