Molecular communication is an emerging paradigm that enables communication through biochemical signals, bridging the gap between digital systems and biological processes. This interdisciplinary field integrates communication technologies with synthetic biology, nanotechnology, and biomedical engineering, offering promising solutions for in-body sensing, targeted therapy, and intelligent health monitoring. As the field progresses from theoretical models to experimental validation, its applications in smart health are becoming increasingly tangible. To support this momentum, the International Graduate Workshop on Molecular Communication and Smart Health provides a platform for graduate students and young researchers to engage with cutting-edge developments at the intersection of bio-inspired ICT and ICT-driven biomedicine. By promoting cross-disciplinary dialogue and fostering the next generation of researchers, this Workshop contributes to the core vision of BICT 2025—advancing innovation where biology and communication technologies converge.
