Blood filter made of nanofibers promises to replace dialysis machines

Japanese scientists have just created a type of nanofilament mesh that can be used to replace the current dialysis method in patients with kidney failure.

Renal dialysis is the most common treatment for patients with kidney failure. This method involves using a dialysis machine to purify toxins from the blood, replacing the normal function of the kidneys.

However, experts at the National Institute of Materials Science said that dialysis equipment often has to use electricity, requires careful maintenance and less common in poor countries so they want to find a way. Less expensive alternatives.

In the new invention, the researchers combined blood-compatible polymers made from EVOH with zeolite, a honeycomb-rich mineral (with countless tiny holes) capable of absorbing dirt in the blood. . They then used electrochemical rotation techniques to create the nano-grid from the polymer and zeolite mixture mentioned above.

Experiments on the ability to purify the blood of nano membranes showed that zeolite minerals helped absorb blood creatinine waste very effectively. Researchers believe that a new type of nano-mesh can be used to create a compact dialysis product that kidney failure patients can wear on their arms, helping them save time and money without resorting to devices. Dedicated expensive and cumbersome.
