‘Sensing Technologies: Biosensors’ is the inaugural meeting in a new Nature (Flagship) Conference biennial series on sensing technologies. This editorially led event will bring together academic and industrial leaders, along with the next generation of researchers, to explore and shape the future of biosensing. The program covers all sensing modalities, from CRISPR-based and electrochemical to nanomaterial approaches. Sessions are organized around Materials, Devices, Systems, and Applied Biosensing, creating a platform for collaboration, discussion, and the exchange of ideas across this interdisciplinary and rapidly evolving field.
