Scientists develop a bacterial prison

Controlling and moving the position of bacteria is a difficult task in both medical applications and research experiments, because the gliding movement of bacteria has its own rules. Bacteria can pass through many media together with nutrients required by human body. In the past, if you want to completely isolate bacteria, it was necessary to isolate the nutrients needed by human at the same time. Now, researchers at Brookhaven National Laboratory have developed a kind of hydrogel fiber, which is a hollow fiber that can isolate bacterial cells without affecting the progress of nutrients.
