A new method of minimally invascope extraction of tissue fluid has been introduced

between cells can be used to diagnose and monitor health conditions. A patch made of fine needles can sample the liquid, which is easier and less invasive than regular blood tests, New Scientist reported. Recently, the relevant research results published in Science - Translational Medicine.
intercellular fluid, also known as tissue fluid, is the liquid that surrounds cells. It seeps out of blood vessels into cells, delivers essential nutrients, and removes waste.。 Prausnitz and colleagues developed a patch made up of five stainless steel microneedets that produce small punctures on human skin. They tested the patch on 21 people, using it to remove a small amount of tissue fluid from the body and compare it to blood samples.
two samples, the researchers found similar levels of important compounds, including glucose, caffeine and vitamin D. This means that this method can be used to detect these compounds and diagnose health problems associated with their content, such as diabetes. Because the needles in the patch are much smaller than normal needles, the needle eyes on the skin can heal in a day.
the traditional method of extracting tissue fluid from the body, need to fight against blood pollution. To solve this problem, Prausnitz and the team slightly increased the suction power of the patch to ensure that no blood vessels ruptured near the pinhole.
may be more acceptable than blood tests, especially in pediatric medicine. Timothy Miles Rawson, of Imperial College UK, said: "Since tissue fluids do not condense, it can also be used to continuously monitor various compounds in the body. (Source: Wen Lele, China Science News)
