Nanotherapy: Controlled delivery of chemotherapeutics to fight cancer stem cells

Chemotherapy is one of the most used treatments against cancer, along with surgery and radiotherapy. In a chemotherapy treatment, one or several drugs are administered to the patient to remove or damage cancer cells. Nevertheless, the treatment has several drawbacks that are hard to overcome, particularly the side effects. In this case, the inherent toxicity of the drugs employed causes a variety of symptoms including weakness, nausea and hair loss. As a result, chemotherapy is far from an ideal approach.
