Brain cancer is one of the deadliest cancers, as it is one of the hardest to treat. Treatment usually involves a surgeon having to perform invasive surgery to remove as much of the tumor as possible. This is made even more difficult by issues with medically imagin brain tumors. This is becasue the imaging performed on the brain is imprecise.

Fluorescent Nanoparticles can be injected into a patient, they will localise to the tumor and can be imaged precisely using MRI. This will pave the way for better treatment of brain cancer sufferers. Precise imaging itself will increase patient survival rates as it is so important to succesful treatment of the disease

The next logical step in the fight against brain cancer is to make these fluorescent nanoparticles toxic to the tumor cells. Thereby eliminating the tumor without having to perform invasive surgery.- CT
