Updated On: Nov 12, 2026
- Au-Nps
- Pt-Nps
- Ag-Nps
- Si-Nps
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Some metal nanoparticles act as disinfectants because they damage bacterial cells.
Step 2: Known Use
Silver nanoparticles (Ag-Nps) have strong antibacterial action and are used in water purification.
Step 3: Compare the options
Au, Pt and Si nanoparticles are not used for this. The answer is option (C).
Final Answer:
Silver nanoparticles are used to remove E. coli from water. \[ \boxed{\text{(C) }\text{Ag-Nps}} \]
