IDENTIFYING CANCER BY JUST ONLY DROP OF BLOOD

IDENTIFYING CANCER BY JUST ONLY DROP OF BLOOD

WHY WE NEED THIS TECHNOLOGY: 

 Cancer is one of the most dengarous disease in mordern age.we have not any permanent cure of that diseases,we need to detect that early fore better cure.some types of cancer, such as ovarian cancer,tends to remain undecteted until they reached too advanced stage.its a big problem for us to detect that kind of cancer. so we need and better and efficient way to detect cancer. for a middle class person it's not possible to maintain his full body checkup frequently because the checkup is costly and also takes so much time.

NEW INNOVATIVE TOOL:

  This tool may be able to detect cancer easily,quickly,and in minuscule amounts of blood.it is a new development highly sensitive device can detect cancer in very small clinical samples.
in a bid to find a simple, effective way of identifying hard to diagnose cancers, researchers from the university of kanas (KU) cancer center  and KU medical center in kasas city have now developed an ultrasensitive cancer detecting device.

HOW DOES IT WORK: 

 The device, which is called a"3d-nanopatterned microfluid chip," could successfully detect cancer markers in the tiniest drop of blood or in a component of the blood called plasma.
Lead author Yong Jeng,an associate professor of chemistry at KU, and his team describe how the noble tool works in a paper that the journal nature biomedical engineering has published.
this device,the scientist explain This device, the scientists explain, identifies and diagnoses cancer by "filtering" for exosomes, which are tiny vesicles that some eukaryotic cells produce.

In the case of cancer cells, exosomes contain biological information that can direct tumor growth and spread."Historically, people thought exosomes were like 'trash bags' that cells could use to dump unwanted cellular contents," Zeng explains. "But, in the past decade," he adds, "scientists realized they were quite useful for sending messages to recipient cells and communicating molecular information important in many biological functions."

"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 really active compared to normal cells," Zeng notes.
