Question

Write the name of nanoparticle which acts as highly effective bacterial disinfectant.

Hint:

Silver has been used since ancient times for its medicinal properties; the "nano" form simply provides a much larger surface area for reaction, making it more efficient.

Answer 1

Step 1: Understanding the Concept:
Certain metal nanoparticles exhibit antimicrobial properties due to their high surface-to-volume ratio, allowing them to interact effectively with microbial cell membranes.
Step 3: Detailed Explanation:
Silver (\(Ag\)) nanoparticles are well-known for their potent antibacterial, antifungal, and antiviral activities.
They release silver ions which damage the cell wall and metabolic pathways of bacteria, leading to their death.
They are used in wound dressings, water purifiers, and consumer products for disinfection.
Step 4: Final Answer:
The nanoparticle is Silver (\(Ag\)) nanoparticle.
