- Silver
- Copper
- Titanium
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Gold microparticles are used in gene gun delivery methods because they are chemically inert, biocompatible, and provide a stable platform for attaching DNA. These properties ensure efficient DNA delivery into cells without causing significant cytotoxicity.
