The Bragg wavelength shift ∆λB of biofunctionalized eFBG fibers as a function of CRP concentration (i) without any interfering substances (black), (ii) in the presence of the interfering substances urea (1.8 g/L) and ascorbic acid (1.8 g/L) (grey), (iii) without fiber coupling of the CRP-specific aptamer and any interfering substance (brown), and (iv) in presence of diluted CRP deficient human plasma (blue). Data were fitted to the Langmuir–Freundlich isotherm. Reproduced under the terms of the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/) [145].
