Abstract: 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.

Abstract: Provided is an immune microbubble complex, and a use thereof. An immune-microbubble complex (IMC) according to the presently claimed subject matter includes microbubbles to which an antibody is conjugated, in which the microbubbles have excellent stability and excellent antibody binding strength, and it was confirmed that, when the immune-microbubble complex is treated with high-intensity focused ultrasound (HIFU), an anti-tumor effect is significantly increased and an immune-enhancing effect is exhibited. Therefore, the immune-microbubble complex according to the presently claimed subject matter is expected to increase the efficiency of delivering the conjugated antibody and be used in both diagnosis and treatment of cancer, and exhibit various functions in the field of immunotherapy, including a contrast effect, half-life improvement, improved drug delivery, a lymphocyte concentration effect, cancer immunotherapy and induction of immunotherapy using ultrasound.
