Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

open access: yesChemistry – A European Journal, EarlyView.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.
