Legumain is a protease found expressed in tumour cells and may be useful in the specific targeting of chemotherapeutics to tumour cells. Here, the authors design nanoparticles that are loaded with doxorubicin and contain a legumain cleavage site; once the nanoparticles enter tumour cells legumain activity results in the release of doxorubicin.
