New technique for cancer treatment by light sensitive drugs

New technique for cancer treatment by UK researchers
Question: Researches of which of the following country recently came out with new technique of effective and less expensive treatment of cancer?
(a) USA
(b) France
(c) UK
(d) China
Answer: (c)
Related facts:
  • UK based researchers developed a path breaking light-based cancer treatment, which is effective, less expensive and safer for patients.
  • The study was carried out at the University of Sheffield of UK by an interdisciplinary team of researchers.
  • The team used tiny carbon nanoparticles that can deliver cancer drugs to tumor. This kind of treatment is based upon light sensitive drugs, which become active and destroy the cancer cells only when exposed to light.
  • Light-based or photodynamic therapy is already a clinically-approved treatment. Many of these drugs are frequently toxic even without light and may cause side effect in patients and leading to treatment failure.
