The present application is also directed to a cargo delivery complex comprising a CPP and a cargo molecule wherein the peptide further comprises a targeting sequence selected from the group consisting of GYVSK, GYVS, YIGS and YIGSR. Methods of making and using the cargo delivery complexes are also disclosed.

Composition for hepatic arterial chemoembolization using human serum albumin nanoparticles carrying anticancer agent, and method for producing same

The present invention aims to dramatically increase the effect of hepatic arterial chemoembolization by developing human serum albumin-based nanoparticles, which are bioproteins that effectively carry Adriamycin in place of Adriamycin, an anticancer agent used in hepatic arterial chemoembolization. The human serum albumin nanoparticles carrying the Adriamycin not only intensively infiltrate the drug effectively into the cells but also have a synergistic effect that can induce a long-term therapeutic effect by utilizing the effect of continuous drug release from the particles.
