The device can detect which strain of malaria is in the blood
Scientists from Glasgow University claim they have created a device which can detect malaria within minutes.
Doctors have welcomed the development as more travellers go abroad without taking proper precautions against the disease.
The flu-like symptoms can be missed until the patient is critically ill.
Blood samples are placed in the microchip, which is designed to detect the strain of disease. This means the best drug can be used to treat it.
Last year a study revealed more cases of the most dangerous type of malaria than ever before are being brought back to the UK from trips abroad.

The Health Protection Agency study identified 6,753 cases of falciparum malaria diagnosed between 2002 and 2006.
Experts said many of the cases arose from visits to west Africa made by people visiting relatives and friends.
Project leader Dr Lisa Ranford-Cartwright said: "The current way of diagnosing is using a blood smear on a slide and examining it on a microscope.
"That will take a good microscopist a good hour to reach a diagnosis, it's extremely difficult to make that diagnosis accurately.
"The chip can give us a result in as little as half an hour."
Dr Heather Ferguson, a malaria researcher, picked up the disease in southern Kenya and it was only spotted by chance when she was giving a blood sample.
She said: "Had I not been diagnosed at that moment and caught it within the next 24 hours all those millions of parasites would have replicated one more time, making eight times as many as there had been before, which could very easily have been lethal."
