So, imagine if you have a really cool toy made out of metal. Now, what if I told you that this toy could magically disappear by itself? Pretty amazing, right? Well, that's kind of what bioabsorbable metallic glass is!
You see, metallic glass is a special type of metal that is made by cooling it down very quickly. This makes it really strong and durable, just like regular metal. But scientists have found a way to make this metallic glass disappear over time when it's inside our bodies. It's like a magic trick!
But why would we want metal that disappears? Well, sometimes doctors need to put things inside our bodies to help us get better. It could be things like screws or plates to fix our broken bones or stents to keep our blood vessels open. These things are usually made of regular metal, but they have some drawbacks.
One problem with regular metal is that it can stay in our bodies forever. This can cause some issues because our bodies might not like having foreign objects inside for a long time. Sometimes, our bodies can have a reaction to these foreign objects, and it can even lead to infections or other complications.
But with bioabsorbable metallic glass, doctors can use it for these medical devices, and since it disappears over time, we don't have to worry about taking it out later. Isn't that cool?
Now, you might wonder how this metallic glass disappears. Well, it's designed to break down gradually when it's exposed to certain fluids in our bodies, like water. These fluids help to change the structure of the metallic glass, making it weaker and causing it to dissolve little by little. So, just like when a sugar cube dissolves in water, this metallic glass slowly dissolves in our bodies!
This makes it really safe because as the metallic glass dissolves, our bodies can absorb it or get rid of it in a natural way. It's like the toy I mentioned earlier that disappears on its own. It's there to help us, but then it goes away when it's no longer needed.
So, bioabsorbable metallic glass is like a disappearing metal. It's made to help doctors fix our bodies, and then it goes away by itself over time. It's an incredible material that can make a big difference in medicine and help us heal better.
