Question

........... nanoparticles are extraordinarily efficient for clinical diagnostic purposes as they give strong signatures in optical absorption, fluorescence spectroscopy, X-Ray diffraction, and electrical conductivity.

• A. Silver
• B. Copper
• C. Gold
• D. Iron

Hint:

Gold nanoparticles are commonly used in diagnostic applications due to their unique optical properties and ease of functionalization.

Answer 1

The Correct Option is C

Gold nanoparticles are widely used in clinical diagnostics due to their strong optical properties, such as high absorbance and scattering, which are useful for optical imaging techniques. They also exhibit good fluorescence properties and can be easily functionalized for use in diagnostics, making them the most efficient for clinical applications.
Final Answer: \[ \boxed{\text{(3) Gold}} \]
