Scientists at Newcastle University have developed a cancer fighting technology which uses ultra-violet light to activate antibodies which very specifically attack tumours. Therapeutic antibodies have long been recognised as having excellent potential but getting them to efficiently target tumour cells has proved to be very difficult. Now, Professor Colin Self and Dr Stephen Thompson from Newcastle University have developed a procedure to cloak antibodies which can then be activated by UV-A light and so can be targeted to a specific area of the body just by shining a probe at the relevant part.
