Researchers at the University of Kansas have come up with a new cancer diagnostic device, which allows doctors to quickly detect the disease by analyzing a patient's blood or plasma drop, shortening the diagnosis and starting the treatment.
The new device, called lab-on-a-chip, is based on the monitoring of exosomes, cell-derived micro-sacs that transmit information from cancer cells to stimulate tumor growth in the body.
"In the past, it was thought that ezosomes looked like garbage bags used by cells to get rid of unwanted cellular material, but over the last decade they have been beneficial," said Yong Ching, assistant professor of chemistry at the University of Kansas. The transmission of messages to the receiving cells and the transmission of important information on many vital functions. "
Mr. Cheng said that the invention of a laboratory on a chip was based on three-dimensional microengineering techniques. His idea is to expose the exosomes to the surface of the chip through a more efficient process called mass transfer.
The team tested the new device on samples of patients with cancer of the uterus and discovered that the flea could detect the presence of cancer in a very small amount of plasma extracted from the patient's body.
