“…On the other hand, depending on the chemical structures and concentrations of backbone matrices used in the fabrication of DMNs, the dissolution time varies from minutes to hours, leading to inconvenience, irritation, and allergic reactions in some patients [ 15 ]. Therefore, various innovative systems, including double-layered and tip-loaded DMNs, arrow-head DMNs, physical and chemical application enhancers, and DMN applicators, have been developed to overcome the current patch-based DMN limitations [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. However, double layer and tip-loaded DMNs are limited by low loading capacity and complexities that limit their use as an optimal platform for DMNs [ 23 , 24 , 25 , 26 ].…”
