Cancer is a disease characterized by the uncontrolled growth and spread of abnormal cells, and is still the second most common cause of death worldwide. Current treatment for cancer includes surgery, radiation, hormone therapy, and chemotherapy. Chemotherapy forms a major strategy for treating the disease. Conventional chemotherapy is highly nonspecific in targeting the drug to cancerous cells, making the normal healthy cells vulnerable to the drug’s undesirable effects. This significantly hampers the maximum allowable dose of the drug. Moreover, rapid elimination and specific distribution into targeted organs and tissues necessitate the administration of large dose of drug, which is not economical and often results in untoward toxicity issues.1,2 Nanoparticles (NPs) are customized drug delivery vectors capable of preferentially targeting large doses of chemotherapeutic agents or therapeutic genes into malignant cells while sparing healthy cells. NPs hold great promise of drastically changing the face of oncology by their ability of targeted delivery, and thereby, overcoming limitations of conventional chemotherapy, which include undesirable biodistribution, cancer cell drug resistance, and severe systemic side effects.
