Developed 3-D nano networks, “nanosponges” can be tailored in their size, linear release profile of drugs and are easily functionalized with targeting, labeling and cell penetrating units. Hydrophobic drug molecules can be incorporated in a postloading procedure, allowing for single and multi-drug incorporation. The resulting particles are well dispersed in aqueous solutions for in vitro and in vivo applications.
These properties and features of the delivery system have contributed to enhance drug solubilization, increased efficacy in models of lung, brain and breast cancer and in eye diseases such as glaucoma. The delivery system is further investigated in the targeting of islet cells and in the treatment of diabetes and in the development of hybrid-combination treatments.
