Targeting tumours with graphene oxide

Abstract:
Yongsheng Chen from Nankai University, China, and colleagues have developed a delivery system using functionalised graphene oxide as the drug carrier. Graphene oxide has a very high surface area, enabling it to transport a large amount of the drug. As cancer cells are typically more acidic than normal cells, the team developed the system to increase drug release as pH decreases. This confines the drug to the tumour site and limits uptake by healthy cells. This could allow doctors to use higher doses and improve the effectiveness of treatments, or reduce side-effects for patients.
