Graphical Abstract
Uniform 100-nm megranate-like FeCo/gelatin nanospheres are self-assembled through the efficient chelation of small primary FeCo NCs with gelatin polypeptide chains in a one-pot reaction (see image). The unique nanospheres efficiently combine rapid magnetic response, huge active surface, and high capacity of controlled loading and releasing of DNA molecules.
