1. Artificial hips and knees
2. Stethoscopes for listening to a heartbeat
3. Special bandages for wound healing
4. Artificial heart valves
How can soft biomaterials, like gels and polymers, be used in medicine?
1. They are used to create strong, permanent bone replacements.
2. They can deliver medicine slowly inside the body over time.
3. They respond to body temperature to perform surgery.
4. They are primarily used to build the framework for artificial organs.
What is a key feature of "smart" biomaterials described in the essay?

4. They are only used for dental implants.
The essay concludes that the future of biomaterials will most likely involve
1. replacing the need for doctors and surgeons
2. becoming more advanced and offering new hope for better medical care.
3. focusing only on the development of artificial joints.
4. being used less often due to safety concerns.
