The significant advances in nano-drug delivery systems (NDDS) for anticancer agents have led to the development of computational techniques, such as machine learning and neural networks to identify the optimal architectural and compositional design in a wide variety of therapeutic nanoformulations. On the other hand, few studies have examined downsized plug-in reaction-ware embodied in an autonomous platform for the instant reconfigurable production of engineered nanomaterials to guide optimal NDDS designs and delivery strategies. This paper describes an on-demand system for an electrically operable, continuously processible material produced by sequential spray pyrolysis and vibrating spray for single-pass NDDS assembly. In particular, a mild chemotherapeutic NDDS consisting of amorphous boron nitride (a-BN; a stable base material for loading), doxorubicin (DOX; an anticancer drug), and folic acid-chitosan conjugate (FACHI; a targeting and antiopsonic agent), called a-BN-DOX@FACHI, was fabricated using the developed system. a-BN-DOX@FACHI was assessed for the pH-responsive release of DOX, targeting of the folate receptor, and its resistance to opsonization and macrophage phagocytosis. a-BN-DOX@FACHI was found to be a mild cancer chemotherapeutic with reasonable biosafety. Integrating a metal ablation device with the developed on-demand system enabled the reconfiguration of NDDS from a-BN-DOX@FACHI to a-BN-Au-DOX@FACHI or a-BN-Pt-cisplatin@bovine serum albumin to add a photothermal effect with a range of architectures and compositions.
