UPSC Prelims 2015 Question:

With reference to the use of nanotechnology in the health sector, which of the following statements is/are correct ?

1. Targeted drug delivery is made possible by nanotechnology. 
2. Nanotechnology can largely contribute to gene therapy. 
   
   

Select the correct answer using the codes given below.

Explanation:

• Nanotechnology has countless applications in different fields. In health and biomedical areas, it can be used in drug delivery and therapeutics. Nanocarriers are used in nanotechnology for targeted, triggered, and controlled delivery of drugs or other therapeutic molecules. There are Different targeting strategies used (active or passive) and conjugation methods. So, statement 1 is correct.
  
  

• The combination of nanoparticles, gene therapy and medical imaging has given rise to a new field known as gene theranostics, in which a nano bioconjugate is used to diagnose and treat the disease. The process generally involves binding between a vector carrying the genetic information and a nanoparticle, which provides the signal for imaging. So, statement 2 is correct.
  
  

Therefore, option (3) is the correct answer.
