Abstract

Objective(s): We used artificial neural networks (ANNs) to optimize a preparation of β-1,3-glucan nanoparticles containing doxorubicin (Dox) through investigating the critical parameters influencing the drug's loading efficiency. Methods: Using an ANNs model, we evaluated the effect of four inputs, involved in preparation of the carrier system, including concentrations of succinic anhydride (Sa), NaOH and polyethyleneimine (PEI) as well as ratio of Dox/Carrier, on loading efficiency of Dox as output parameter, when Dox was conjugated to the carrier (Con-Dox-Glu) or in unconjugated form (Un-Dox-Glu). Results: The model demonstrated that increasing Sa and PEI leads to reduced loading efficiency, while the effect of NaOH on loading efficiency does not appear to be important in both Con-Dox-Glu and Un-Dox-Glu delivery system. Ratio of Dox/Carrier showed complex effects on loading efficiency: while a certain value was required to provide maximum loading efficiency in Con-Dox-Glu, a different critical value was associated with obtaining minimum loading efficiency in Un-Dox-Glu. Conclusions: This study demonstrated the possibility of employing an ANNs model to identify the effect of each parameter on loading efficiency and optimize the conditions to achieve maximum loading efficiency in both conjugated and non-conjugated drug delivery system. © 2021 Nanomedicine Research Journal.
