The present invention relates to nanostructures for penetrating deep into cancer tissues, and more particularly, to nanostructures capable of selectively delivering nanoparticles and drugs to cancer tissues because it is possible to intelligently control the release of the nanoparticles and the drugs depending on the pH condition of the cancer tissues and also having high nanoparticle and drug delivery efficiency because it is possible for the nanoparticles to penetrate deep into the cancer.
