Abstract
This paper presents an immunobiosensor of fast response time to detection of bacteria, made by Plastic Optical Fiber. Probes were tested in U-shaped and Meander-shaped to investigate the best sensitivity, accuracy and repeatability. During calibration was used for sucrose solutions refractive index (RI) from 1.33 to 1.39. This is equivalent to IR range of the water and the highest concentration of bacteria, respectively. Immunobiosensor was able to detecting the presence of enteropathogenic Escherichia coli in water from suspensions of different concentrations of 106 and 104 colonies forming units per millilitre (CFU/mL) in twenty minutes.
