Question

Considering the unique properties of nanomaterials, the development of a new drug delivery system utilizing nanotechnology would likely focus on:

• A. Increasing the size of the drug molecules for easier detection
• B. Enhancing the solubility and bioavailability of poorly soluble drugs
• C. Reducing the effectiveness of drugs to minimize side effects
• D. Focusing solely on external applications to the skin

Hint:

Nanomedicine = better delivery. Nano carriers help dissolve stubborn drugs and boost their performance!

Answer 1

The Correct Option is B

Nanotechnology offers revolutionary advantages in drug delivery, especially by improving the pharmacokinetic properties of therapeutic agents. One major focus is on enhancing the solubility and bioavailability of poorly water-soluble drugs. Nanoparticles can encapsulate these drugs and improve their dispersion in biological fluids, allowing for more efficient absorption and controlled release.
This results in:

• Better drug performance with lower doses.
• Targeted delivery to specific tissues or cells.
• Reduced side effects due to localized action.

Clarification of incorrect options:

• (A) Increasing molecular size often reduces absorption — the opposite of what nanotechnology aims to do.
• (C) Drug effectiveness is typically preserved or enhanced, not deliberately reduced.
• (D) While topical delivery exists, nanotech enables both internal and external delivery systems.

Thus, the key goal of nanotech-driven drug delivery is to enhance solubility and bioavailability, particularly for drugs that are otherwise poorly absorbed.
