Nanoparticles improve tumor treatment in mice

In the treatment of cancer, chemotherapy is a cleaver, not a scalpel. By attacking rapidly dividing cells, chemotherapy effectively fights tumors, but it also ravages healthy cells in the gut, bone marrow, the scalp and other organs, leading to severe side effects. These toxic chemicals save lives, but at a […]
