- Silver
- Gold
- Copper
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Certain metal nanoparticles exhibit strong antimicrobial and antibacterial properties.
Step 2: Application
Silver nanoparticles ($AgNPs$) are widely used in water purification and medical filters because they release $Ag^+$ ions that destroy bacterial enzymes and DNA.
Step 3: Conclusion
Silver is the standard choice for antibacterial coatings in nanotechnology.
Final Answer:(B)
Certain metal nanoparticles exhibit strong antimicrobial and antibacterial properties.
Step 2: Application
Silver nanoparticles ($AgNPs$) are widely used in water purification and medical filters because they release $Ag^+$ ions that destroy bacterial enzymes and DNA.
Step 3: Conclusion
Silver is the standard choice for antibacterial coatings in nanotechnology.
Final Answer:(B)
