Description
Shota Sato and eight co-authors propose a tiny hollow tube made of gel that can sit inside a blood vessel and release drugs there, in 2026 work. Fiber-shaped carriers used before carried a risk of blocking flow and harming tissue. Their tube is made of barium alginate gel, a seaweed-based material that holds a stable network in flowing blood. A catheter delivers the tubes one by one into place.
The team tested the carriers in lab models that mimic vessels and in the kidney arteries of rats. Tubes stayed fixed in place while blood kept passing through the open center. They also delivered a model drug into a small kidney artery as intended. The design points toward targeted treatment inside vessels without cutting off the flow those tissues need.
