article_snippet: But Nanorobots are set to be used to treat a person who is seriously ill with leukaemia.
article_snippet: Nanorobots (pictured) which are made from a DNA 'cage' and hold a payload of drugs, could be used to treat a person who is seriously ill with leukaemia.
article_snippet: a patient who has been given six months to live is set to receive an injection of DNA nanorobots designed to interact with and destroy leukaemia cells without damaging healthy tissue.
article_snippet: Nanorobots can be programmed to independently recognise target cells and deliver payloads, such as cancer drugs, to target cells.
article_snippet: This diagram shows the nanorobot being 'unlocked' so the drugs (shown in purple) are released .
article_snippet: Nanorobots can recognise a small population of target cells within a large population.
article_snippet: George Church, who is involved in the research at the Wyss Institute explained the idea of The robots is to make a ‘cage’ that protects a fragile or toxic payload and ‘only releases The robots at the right moment.
article_snippet: The nanorobot we designed is capable of recognising a small population of target cells within a large healthy population,’ Dr Bachelet continued.
article_snippet: While all cells share the same drug target that we want to attack, only those target cells that express the proper set of keys open The nanorobot we designed and therefore only only those target cells that express the proper set of keys will be attacked by The nanorobot we designed and by the drug.
article_snippet: The team has tested The team technique in animals as well as cell cultures and said The nanorobot we designed attacked these [targets] with almost zero collateral damage.
article_snippet: In the future, Dr Bachelet said people could  be injected with nanorobots at an annual doctor’s check-up (illustrated with a stock image).
