“…Nanomedicines that co-encapsulate multiple drugs are increasingly recognized as useful medications for managing cancers and chronic diseases [ 1 , 2 ]. Examples of nanomedicine that have demonstrated ratiometric co-encapsulation of drug combination include liposomes, such as CPX-351, the antineoplastic liposomal drugs combination (cytarabine and daunorubicin) at the fixed ratio, polymer-based nanocarrier, micelles (e.g., Triolimus) and polymer-lipid hybrid nanoparticles [ [3] , [4] , [5] , [6] , [7] , [8] , [9] ].…”
