Abstract:In this study, we report the engineering of multimodal Liposome-QD hybrids (L-QD) for cancer imaging and therapy. L-QD hybrids were loaded with doxorubicin (Dox) using the osmotic gradient technique, achieving high encapsulation efficiency comparable to liposome alone. Structural elucidation using cryogenic electron microscopy (cryo-EM) clearly showed that QD were incorporated in the lipid bilayer and Dox crystals were encapsulated into the liposome aqueous core. Furthermore, the surface of Dox-loaded hybrids were functionalized with anti-MUC-1 antibody for active targeting, using the post-insertion technique.MUC-1 antibody-targeted L-QD hybrids encapsulating doxorubicin are thought to constitute a potential multimodal system for the simultaneous delivery of therapeutic and diagnostic agents to cancer cells in vitro and in vivo.
