Q: With reference to the use of nano-technology in health sector, which of the following statements is/ are correct?
- Targeted drug delivery is made possible by nanotechnology.
- Nanotechnology can largely contribute to gene therapy.
Select the correct answer using the code given below:
a) 1 only
b) 2 only
c) Both 1 and 2
d) Neither 1 nor 2
The correct answer is Both 1 and 2.
Nanotechnology
- It is the development and the use of techniques to study physical phenomena and develop new devices and material structures in the physical size range from 1 to 100 nanometres (nm).
- 1 nanometre is equal to one billionth of a meter.
- This technology has an impact on almost all sectors of the economy.
- The research on nanotechnology covers many fields like health, food, computing, textile, energy, transport, space, agriculture, etc.
- It has different biological properties from large-sized systems.
- Its biological property could be used effectively to overcome problems in drug and gene therapy. Hence, Statement 2 is correct.
- In drug therapy, we face the problems of inefficacy or nonspecific effects; hence, nano systems are being developed for targeted drug therapy. Hence, Statement 1 is correct.
- The primary challenges in non-viral gene therapy are relatively temporary gene expression and lower effectiveness than viral vectors.
- Research efforts have concentrated on understanding the barriers in gene delivery so that non-viral systems that are as successful as viral systems in gene transfection can be established.
