D) Neither 1 nor 2

Explanation for the Correct Answer
  • “Micro-vehicles” have been constructed for delivering drugs to hard-to-reach structures at the back of the eye. While the surface of the eye can be easily treated through topical administration such as eye drops, these drugs are ineffective for conditions affecting the back of the eye. One strategy for treating the posterior region has been through random, passive diffusion of nanoparticles injected on the surface, where the particles take a long time to travel through the vitreous (eye fluid) to reach their target — during which the drugs can lose efficacy. The new ‘micro-propellers’ circumvent these problems.
  • A global team of scientists in Germany, China and Denmark have constructed “micro-vehicles”.
