The self-adhesive patch is an adaptation of photodynamic therapy treatment (PDT), but uses the latest technology to develop a compact light source. Previous methods of administering PDT have required the patient to lie under a light for several hours to activate anti-cancer creams applied to the skin.
The technology has been developed by a team from St Andrews University and Dundee’s Ninewells Hospital.
The patch contains its own organic light-emitting diode and is suitable for treating only the less serious non-melanoma cancers near to the surface of the skin. The researchers claim that the patch may also be used to treat conditions like acne and may have a cosmetic use to prevent ageing.
