Breakthrough in nanomolecular technologies for solid tumor treatment

The prestigious scientific journal Nature Biotechnology has published in its latest issue an article by researchers from the Arizona State University and the National Center for Nanoscience and Technology of the Chinese Academy of Sciences, who have reported an extraordinary experiment, consisting of developing nanosystems for the treatment of solid tumors. Specifically, the team, led by Yan Liu, has developed a nanostructure named Nanobot (Nano-robot), consisting of DNA fragments folded up to create closed structures, having on their surface a protein usually found on tumor cells’ surface. Subsequently, nanobots have been injected into laboratory mice and miniature pigs with solid tumors. Once in the blood flow, nanobots are carried to tumor cells, and they bind to their surfaces, due to affinity among surface proteins. Nanobots’ structure then opens up and releases a thrombin from within, which functions as a coagulant, in that it clogs the cell’s vessels, and therefore blocks nutrients, killing the cell.
