Dual responsive PMEEECL–PAE block copolymers: a computational self-assembly and doxorubicin uptake study

) of these copolymers and finding appropriate CG mapping for both PMEEECL-PAE and DOX. The output of the MARTINI CG simulations is in agreement with SCF predictions. The results show that DOX is solubilized with high efficiency (75-80%) at different concentrations inside the PMEEECL-PAE micelles, although, interestingly, the loading efficiency is reduced by increasing the drug concentration. The non-bonded interaction energy and the RDF between DOX and water beads confirm this result. Finally, MD simulations and SCF computations reveal that the responsive behaviour of PMEEECL-PAE self-assembled structures take place at temperature and pH ranges appropriate for drug delivery.
