The success of gene technologies hinges on our ability to engineer superior encapsulation and delivery vectors. Cubosomes are lipid-based nanoparticles where membranes, instead of enveloping into classic liposomes, intertwine into complex arrays of pores well-ordered in a cubic lattice. These

Active targeting modification is one of the foremost nanomedicine strategies for the efficacy improvement. Compared to the homogeneous ligandation on spherical nanocarriers, non-spherical nanomedicines usually make the ligand modification more complicated. The modified ligands always exhibit anisotropy and heterogeneity. However
