Correction to: Scientific Reports https://doi.org/10.1038/s41598-021-99099-x, published online 1 October 2021
The original version of this Article contained an error in the legend of Figure 4 which was a duplication of the legend of Figure 5.
“The experimental setup used for the CD44 protein measurements using a fiber optic spherical tip-based biosensor. Surface functionalization steps are shown in the zoomed area. APTMS 3-(aminopropyl)trimethoxysilane, MUA 11-mercaptoundecanoic acid, EDC 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, NHS N-hydroxysuccinimide, OBR optical backscatter reflectometry.”
now reads:
“Studying specificity of functionalized fiber optic tip biosensor for CD44 protein detection by measuring control proteins (IL-4 and thrombin). The reference protein concentration used was 6 pM. (a) Amplitude change of the sensors when measuring target protein vs. control proteins in different concentrations; (b) Response of the sensors normalized to their respective RI sensitivities.”
The original Article has been corrected.
