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:
Nanotechnology utilizes materials at the nanoscale (1-100 nm). Certain metal nanoparticles exhibit enhanced antimicrobial properties.
Step 2: Detailed Explanation:
Silver nanoparticles are widely recognized for their potent antibacterial, antifungal, and antiviral properties.
They release silver ions ($Ag^+$) which interact with the bacterial cell wall and plasma membrane, causing cell death.
They are used in water purifiers, surgical instruments, and bandages to prevent infections.
Step 3: Final Answer:
Silver nanoparticles are used as highly effective bacterial disinfectants.
