摘要：

Here we report a long period grating fiber sensor used to detect β-Galactosidase in water, an enzyme produced by E. coli that can be used to reveal the presence of the bacteria and their concentration. The advantage of this approach is that β-Galactosidase is produced by a vivid bacterium and its concentration is proportional to bacteria concentration. The purpose of this study is to determine the sensitivity of such sensor. The measurement of β-Galactosidase concentration bases on the long period grating fiber high sensitivity at refractive index modifications of the ambient. Tests proved a good concordance between calculations and measurements. © 2021, Politechnica University of Bucharest. All rights reserved.
