Herein we report the synthesis of cellulose nanocrystals covalently bound to a model chemotherapeutic drug (DOXO) via a novel spacer arm, which acts both as linker and as selective releasing agent. The carbamate linkage present in the linker, shows stability in aqueous environments for a wide range of conditions and can only be hydrolyzed in the presence of cells, freeing the active drug, with unmodified chemotherapeutic properties.

Abstract
Herein we report the synthesis of cellulose nanocrystals covalently bound to a model chemotherapeutic drug (DOXO) via a novel spacer arm, which acts both as linker and as selective releasing agent. The carbamate linkage present in the linker, shows stability in aqueous environments for a wide range of conditions and can only be hydrolyzed in the presence of cells, freeing the active drug, with unmodified chemotherapeutic properties.File in questo prodotto:
