For the proper implementation, plastic optical fibers were used to excite the colloid, while the fluorescence signal was collected by another fiber and guided to a spectrometer. Real-time tests were carried out with cyanobacteria cultures, confirming the usefulness of monitoring these autofluorescence changes in the photobioreactor. This device provides a preliminary approach for the characterization and detection of cyanobacteria, demonstrating the feasibility of developing small, practical sensors through a simple fiber configuration for monitoring aquatic ecosystems.}, organization = {This work was supported by the R+D projects INNVAL23/10, funded by IDIVAL; TED2021-130378B-C21, funded by MCIN/AEI/10.13039/501100011033 and European Union NextGenerationEU/PRTR; PID2022-137269OB-C22, funded by MCIN/AEI/10.13039/501100011033 and FEDER, UE; The authors acknowledge the Department of Biology at the Autonomous University of Madrid (UAM) for providing the cyanobacteria cultures and support.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2025, 13639, 136399R}, publisher = {29th International Conference on Optical Fiber Sensors, Porto, Portugal, 2025}, title = {Optical fiber fluorescence sensor integrated into a photobioreactor}, author = {García García, Borja and Fernández Manteca, María Gabriela and Goméz Galdós, Celia and Deus Álvarez, Susana and Monteoliva Herreras, Agustín Pedro and López Higuera, José Miguel and Cobo García, Adolfo and Rodríguez Cobo, Luis}, }
