The use of phthalocyanines together with a free radical source for photodynamic therapy is described. The free radical sources cause the photodecomposition of the phthalocyanines, which can be useful for various reasons such as allowing light to penetrate to lower tissue levels that would otherwise be obscured. The nature of the phthalocyanine and the free radical source chosen can both have an influence on the rate of photodecomposition. The free radical sources can be provided along with the phthalocyanines either in free unattached form, or they can be attached to the phthalocyanines themselves.

酞菁及自由基源进行光动力疗法的方法。自由基源导致
酞菁的光分解,这可以有多种有用的原因,例如允许光线穿透到原本被遮挡的较低组织层。所选择的
酞菁和自由基源的性质都可以影响光分解的速率。自由基源可以与
酞菁一起提供,可以是自由未连接的形式,也可以附着在
酞菁本身上。
