With reference to the use of nano-technology in health sector, which of the

are 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 code(2015)

a) 1 only

b) 2 only

c) Both 1 and 2

d) Neither 1 nor 2

Answer: C

Nanosystems have significantly different biological properties from large-sized systems (e.g. implants or microparticles) that could be used effectively to overcome problems in drug and gene therapy. In drug therapy, we face the problems of inefficacy or nonspecific effects; hence, nanosystems are being developed for targeted drug therapy.In gene therapy using non-viral systems, the main issues are relatively transient gene expression and lower efficiency than viral vectors. Research efforts have focused on understanding the barriers in gene delivery so that non-viral systems can be developed that are as effective as viral systems in gene transfection.
