Nano-patterned chip detects cancer in one blood drop
A research team led by researchers from the University of Kansas and KU Cancer Center has developed a device which could detect cancer in a minuscule amount of blood or blood component. The device, which is called a “3D nano-patterned chip”, identifies and diagnoses cancer by filtering for exosomes, pushing them to meet the surface of the ship for analysis. Exosomes help in sending messages to the recipient cells and communicating molecular information important in many biological functions. In the case of cancerous cells, these contain biological information that can direct tumor growth and spread in case of cancerous cells. Basically, tumors send out exosomes packaging active molecules that mirror the biological features of the parental cells. While all cells produce exosomes, tumor cells are active compared to normal cells. To test the chip’s effectiveness, the researchers used clinical samples from patients suffering from ovarian cancer, a type of cancer ...
