An erratum is presented to correct the calculation of the resonator FWHM and sensor detection limit.

In our paper , the development of a high-sensitivity, low detection limit refractometric sensor has been proposed. The FWHM of the proposed sensor was estimated to be 10-7nm and a detection limit of 10-10 RIU was predicted.
We have recently discovered a mistake in the calculation of the resonator FWHM, the correct magnitude of which has been estimated to be 10-4nm. This affects the minimum detection limit, which as a result is estimated to be 10-7 RIU.
Therefore line 6 in the abstract should read “resolution as low as 10-7 are predicted”; on page 7893, at lines 2 and 3 “the FWHM is 4×10-4 nm and the detection limit is 10-6-10-7 RIU” and at line 4 of the Conclusion, “Detection limits of the order of 10-7 have also been predicted”.
Finally, in Table 1, the last row should be modified as follows:
As a concluding remark, we would like to stress that the microfiber coil resonator still provides the lowest detection limit. Moreover, if the best measured propagation loss is used  in the evaluation of the FWHM, a FWHM of 10-5nm is obtained. Compared to other microresonator sensors, this novel device has potentially the largest Q-factor and the lowest detection limit.
