US researchers develop new, highly accurate diagnostic device for cancer

Researchers at the University of Kansas have developed a new diagnostic device for cancer.
The new device allows doctors to quickly detect the disease by analyzing a patient's blood drop or plasma, thereby shortening the diagnosis and initiating treatment.
The new device, called "lab-on-a-chip", is based on the monitoring of "xosomes", microvascular bags derived from cells that transmit information from cancer cells to stimulate the growth of tumors in the body.
"In the past, it was thought that ezosomes looked like garbage bags used by cells to remove cellular materials," said Young Cheng, an assistant professor of chemistry at the University of Kansas. But over the past decade, it has been very beneficial to transmit messages to the recipient cells and to communicate important information about many vital functions. "
The invention of a "lab on a chip" depends on the engineering techniques of three-dimensional nanoparticles. The idea is to expose the "xosomes" on the surface of the chip by 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.
