Topic: Preparation of Multifunctional Calcium Alginate Microspheres by a One-step Electrospray Method for Chemoembolization

Abstract: Embolic agents with narrow size distribution and wide scale range are highly required in transarterial chemoembolization. In this study, a one-step electrospray technique has been developed for the preparation of nano-in-micron multifunctional embolic microspheres. Monodisperse calcium alginate (CaAlg) microspheres with a particle size range of 180 to 1000 μm were fabricated for the embolization. Nanoparticles, such as tantalum, BaSO4 and Fe3O4, were incorporated into the microspheres to realize the medical image diagnoses. Doxorubicin hydrochloride was bonded to CaAlg microspheres to prepare drug-eluting beads for the chemotherapy. They were evaluated for the ability of chemotherapy by investigating the drug loading behavior, the encapsulation efficiency, the cytotoxicity, in vitro and in vivo release under different experimental conditions. The cell viability and hemocompatibility assays indicated the CaAlg microspheres possessed excellent biocompatibility. DSA and histological studies demonstrated the microspheres exhibited good embolization efficacy. In vivo assessment showed that the microspheres had long-term X-ray / NMR imaging capability. They could not only display their own location and distribution precisely in real time during the operation of transcatheter arterial embolization, but also carry out noninvasive examination after operations. These results suggest that the “3-in-1” microspheres combined with embolization, chemotherapy and image diagnoses can be envisioned in the treatment of advanced hepatocellular carcinoma.
