Abstract: Cubosomes are nanostructured lipid-based particles that have gained significant attention in the field of drug delivery and nanomedicine. These unique structures consist of a three-dimensional cubic lattice formed by the self-assembly of lipid molecules. The lipids used to construct cubosomes are typically nonionic surfactants, such as monoolein, which possess both hydrophilic and hydrophobic regions, allowing them to form stable, water-dispersible nanoparticles.

Cubosomes are nanoparticles composed of a specific combination of some types of amphiphilic molecules like lipids, such as phytantriol (PHY), and a nonionic polymer, like poloxamer (F127). Cubosomes have a high hydrophobic volume (> 50%) and are good candidates for drug delivery systems. Due to their unique structure, these nanoparticles possess the ability to incorporate highly hydrophobic drugs.

One of the main toxicities associated to intravenous administration of amphiphilic drugs is pronounced hemolytic activity. To overcome this limitation, we investigated the anti-hemolytic properties of polymeric micelles of Pluronics, triblock copolymers of poly(ethylene oxide) and poly(propylene oxide). We studied the encapsulation of the amphiphilic compound miltefosine (HePC) into polymeric micelles of Pluronics F108, F68, F127, L44, and L64.
