Smart implants dissolve after healing

The video discusses the development of biodegradable metal implants that can dissolve safely in the body, reducing complications associated with permanent metal fixtures. Led by Jag Sankar at North Carolina A&T State University, the team is creating magnesium-based alloys for medical devices like plates and screws. These alloys are designed to biodegrade after healing, eliminating the need for surgical removal. The research involves testing various alloys and applying bio coatings to control dissolution rates. The goal is to make implants that adapt to individual needs and eventually disappear, avoiding issues like setting off metal detectors.

What is the main problem with traditional metal implants used in surgeries?

• They are difficult to manufacture.

• They are not strong enough.

• They can cause complications if left in the body.

• They are too expensive.

Which metal is primarily used in the development of new biodegradable implants?

• Aluminum

• Iron

• Magnesium

• Copper

Why is magnesium considered an ideal building block for biodegradable implants?

• It is very cheap.

• It is lightweight.

• It is non-reactive.

• It is used by the body to build bone and muscle.

What is the purpose of bio coatings applied to magnesium alloys?

• To make them more colorful.

• To prevent them from dissolving too quickly.

• To increase their weight.

• To make them magnetic.

What is the expected future benefit of using biodegradable metal implants?

• They will not set off metal detectors.

• They will be available in more colors.

• They will be cheaper than current implants.

• They will be easier to install.
