ANSWER: Both 1 and 2
Explanation:
- Bio-Glass can be made in a biodegradable ink form, enabling the researchers to 3D print it into structures that are tiny, biodegradable scaffolds.
- It also displays self-healing properties when it gets damaged, which could make it a more resilient and reliable implant.
- When implanted, the combination of the structure, stiffness and chemistry of the bio-glass would encourage cartilage cells to grow through microscopic pores.
- Thus it has the potential to encourage cartilage cells to grow in the knees, which was not possible till now.
- Over time the scaffold would degrade safely in the body, leaving new cartilage in its place that has similar mechanical properties to the original cartilage.
- Bioglass also finds application in drug delivery, as antibacterial agent, as remineralization element and in bone tissue engineering.
