One of the problems with photodynamic therapy is that patients may remain over-sensitive to light for weeks afterwards, or even suffer from burns in tissue close to the target area. Now, research scientists in Canada have taken a step forward by using an enzyme found in specific cancer cells to help light a "photodynamic molecular beacon" inside the cell. The method may make it easier to target tumors without damage to surrounding healthy tissue.
