With reference to the use of nanotechnology in health sector, which of the following statements is/are correct?<br/>1. Targeted drug delivery is made possible by nanotechnology.<br/>2. Nanotechnology can largely contribute to gene therapy.<br/><br/>Select the correct answer using the codes given below.

1. Targeted drug delivery is made possible by nanotechnology. Nanoparticles can be engineered to carry drugs to specific tissues/cells, improving targeted delivery and reducing side effects. Verdict: Correct.

2. Nanotechnology can largely contribute to gene therapy. Nanocarriers such as liposomes and polymer nanoparticles help deliver genes/siRNA safely into target cells, so nanotechnology is an important tool in gene therapy. Verdict: Correct.

Since both 1 and 2 are correct, the answer is (c).
