Geometric aspects in a novel plastic optical fiber biosensor system

Cells detection plays a crucial role in clinical specimens analysis and in food and water microbiological quality control. However, current employed methods demand time and material, raising the analysis procedure costs. Plastic Optical Fiber (POF) biosensors consist in a viable alternative for rapid and inexpensive scheme for detection. In this study, a series of optical fiber taper sensors were prepared using a proprietary tapering machine, and the obtained geometric dimensions dispersion is evaluated, aiming to achieve the best tapering characteristics which will provide a better sensor response — in other words, an increased sensitivity.
