A research team at Tohoku University has published a new study highlighting recent advances in multifunctional fiber technologies for neurochemical sensing and modulation in the brain.
The study was led by Yuanyuan Guo, Associate Professor at the Frontier Research Institute for Interdisciplinary Sciences (FRIS) and the Graduate School of Biomedical Engineering at Tohoku University, who heads the Biofibertronics research group. The research was carried out in collaboration with a graduate researcher, Adrijana Savevska, from the University of Maribor. Adrijana Savevska joined the team through the Erasmus+ Programme traineeship and contributed to the review and analysis of emerging fiber-based electrochemical neural interfaces.
The article reviews recent progress in integrating electrochemical sensing and modulation with thermally drawn multimaterial fibers, flexible bioelectronic platforms that combine optical, electrical, and chemical functions in a single device. Such technologies hold promises for advancing neuroscience research and for future biomedical tools that can monitor biochemical signals in living tissues.
This work also demonstrates the important role of international student exchange in advancing interdisciplinary research. By hosting visiting students and young researchers, the Biofibertronics group at Tohoku University continues to foster global collaboration and train the next generation of scientists working at the intersection of materials science, bioelectronics, and neuroscience.
The work is published in Bioelectrochemistry on December 29, 2025, and was conducted through international collaboration and student exchange.
