It may soon be possible to test a person for cancer with just a drop of their blood and a small machine. As part of a European research project, scientists have developed a device for detecting the HSP70 protein, which is over-expressed in patients with many types of cancer. The objective: to make a diagnosis extremely early in the disease process, thereby improving outcomes for patients.
The Spedoc platform requires only a drop of the patient’s blood. The blood is inserted in a chip that contains many microchannels. Inside each of the channels are tiny and circular structures made out of gold, with a particular “anti-body” surface chemistry that is designed to “trap” HSP70. As the blood flows through the channels, the HSP70 proteins are trapped by the structures, of which there are thousands in the pathway that the blood follows through the chip.
