Research by Chenyang demonstrates the use of "Chemodynamic" therapy where the Fenton reaction is initiated in a region where a tumor is present to attack cancerous cells. In this research paper, many numerous benefits of this new type of cancer therapy were discussed such as its selectivity towards the tumor itself. It was further demonstrated that this therapy can be coupled with other types of cancer therapy to maximize tumor removal. Research by Xingyang has proven that the Fenton reaction is a viable method of damaging cancerous cells. Fe 2+ in the cell reacts with the produced Hydrogen Peroxide under an "acidic microenvironment" due to the low pH requirements of the Fenton reaction shown in the results above.
