ABSTRACT
DNA origamis provide plenty of platforms for constructing drug-delivery systems in nanoscale. In this work, we developed triangular DNA origami in 120nm around by M13mp18 DNA strand scaffold propagated in E. coli ER2738, which shows desired thermodynamic stability and well biocompatibility. It is tested the proposed DNA origami performance on loading doxorubicin, which is a chemotherapy medication used to treat cancer. In cell intervention experiments, the obtained complex with doxorubicin achieve acceptable performances on penetrating ovarian cancer cells and inhibiting production of A2780 ovarian cancer cells. This DNA nanotechnology provides an efficient nanoscale drug delivering systems or drug cargo system for inhibiting the reproduction of ovarian cancer cells in vitro.
