light therapy

Photodynamic therapy is a rather clever way of activating drugs by laser light, such that they only become effective at the precise location where you want them to act. It is routinely used in treatment of age-dependent macular degeneration and some cancers, but there could be additional benefits in cancer therapy, if only the light could penetrate deeper into tissues.

Oxford chemist Harry Anderson and his team have now demonstrated a new approach that promises to improve the method significantly and broaden the range of its applications. Read my story here.
