The glymphatic system enables the cerebrospinal fluid that surrounds the brain to enter perivascular spaces alongside arteries. Cerebrospinal fluid can then mix with the interstitial fluid that ...

Using an array of tiny needles that are almost too small to see, researchers have developed a minimally invasive technique for sampling a largely unexplored human bodily fluid that could potentially ...

Researchers have developed a new type of porous microneedle that can extract interstitial fluid from skin faster than ever before, without drawing blood or causing pain. By precisely controlling the ...

The fluid between our cells could be used to diagnose and monitor health conditions. A patch made of tiny needles can sample this liquid and could be easier to use and less invasive than normal blood ...
