'Smart implants' dissolve after healing

The video discusses the development of biodegradable metal implants that dissolve safely in the body, reducing complications associated with permanent metal fixtures. Led by Jag Sankar and his team at North Carolina Agricultural and Technical State University, the research focuses on magnesium-based alloys for medical devices. The process involves creating a material database to customize implants for different needs. Bio coatings are applied to control the dissolution rate, and CT scans monitor the disintegration process. The goal is to have these implants replace traditional metal ones within the next decade.

What is the main goal of the research conducted by Jag Sankar and his team?

• To reduce the cost of metal implants

• To develop metals that can dissolve safely in the body

• To create permanent metal implants

• To enhance the strength of existing metal implants

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

• It is the strongest metal known

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

• It is resistant to corrosion

• It is the cheapest metal available

What is the purpose of creating a material database for magnesium alloys?

• To reduce the number of experiments needed

• To cater to different needs based on age and gender

• To find a one-size-fits-all solution

• To store information about all metals

What role do bio coatings play in the development of magnesium alloys?

• They make the alloys more colorful

• They prevent the alloys from dissolving too quickly

• They make the alloys more expensive

• They increase the weight of the alloys

How are CT scans used in the research of biodegradable implants?

• To enhance the color of the implants

• To make the implants more durable

• To monitor the disintegration process over time

• To increase the size of the implants
