Medical tools can easily get infected by germs and mold. This is a big problem. Scientists have been working on special coatings to stop these infections. But, they often miss the mold part. Now, a new coating is here. It uses two special molecules: sulfobetaine and borneol. Together, they make a strong shield. This shield can stop both germs and mold. It can also s...

A new method has been developed to create stronger hydrogels for repairing soft tissues. This method uses tiny fibers made of hydroxyapatite, a mineral found in bones, to reinforce a hydrogel made from polyvinyl alcohol and sodium alginate. These fibers are so small that they can fit into the tiny spaces within the hydrogel's structure. This makes the hydrogel much s...
