Carbon nanotubes give cancer drugs a boost
Both graphene oxide and single-walled carbon nanotubes were found to enhance cancer-cell death in lung-cancer cells when combined with the Paclitaxel, indicating a synergistic effect that has been identified as reactive-oxygen species dependent.
Combination therapies, where more than one therapeutic agent is used to treat a cancer, were first developed to tackle heterogeneity in tumours – that is the presence of more than one type of cell. Typically this involves combinations of different drugs, but the use of carbon-based nanomaterials instead could lower the side effects experienced by patients, while still offering enhanced treatment effects.
