Algae: The answer to chemotheraphy

First of all chemotherapy is a treatment using toxic chemicals to kill cells, especially disease-causing cells like carcinogens. But chemotherapy doesn't always succeed for the host, because it uses toxic drugs, some cells are also affected.
But thanks to a genetically-modified algae named Diatom biosilica, the chemotherapy drugs can be delivered safely in the body, without harming the other cells.
