Question map
With reference to the use of nanotechnology in 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 code given below.
Explanation
The correct answer is option C because both statements are correct.
**Statement 1 is correct:** Nanotechnology has revolutionized the field of drug delivery by providing an effective and targeted delivery of drugs, minimizing side effects, and increasing the therapeutic efficacy of drugs.[1] The application of nanotechnology in drug delivery involves the use of nanoparticles that are designed to carry drugs and deliver them to the desired site of action.[2] Nanoparticles with a size of 1–100 nm are unique since they can pass cell membranes and cause characteristic reactions within cells, affecting both the cell structures and organelles.[3]
**Statement 2 is correct:** Gene therapy, combined with nanotechnology, holds great potential as an innovative approach to tackling numerous severe and untreatable illnesses, namely cancer.[4] Using nanotechnology that enabled mRNA-based COVID-19 vaccines, a new approach to gene therapy may improve how physicians treat inherited forms of blindness.[5] This demonstrates that nanotechnology can indeed contribute largely to gene therapy applications.
Therefore, both statements 1 and 2 are correct, making option C the right answer.

PROVENANCE & STUDY PATTERN
Guest previewThis is a classic 'Applications of Emerging Tech' question. It rewards general awareness over rote memorization. In Science & Tech, if a technology is broadly transformative (like Nanotech or AI), its potential applications in major sectors like Health are almost always 'True' unless the statement implies exclusivity or violates basic physics.
This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.
- Directly states nanotechnology enables effective, targeted delivery of drugs.
- Links targeted delivery with reduced side effects and increased therapeutic efficacy, supporting the statement.
- Explicitly lists 'Targeted drug delivery system' and related mechanisms (active targeting, EPR, controlled release).
- Positions targeted delivery as a central keyword and focus of nanocarrier research, reinforcing the claim.
- Notes nanostructures (1–100 nm) can pass cell membranes and act within cells, a mechanism enabling delivery to specific sites.
- Highlights intrinsic functions of nanomaterials that make them essential in biomedical applications, implying targeted delivery capability.
The modified drug policy explicitly promotes R&D in the drug sector and grants regulatory/exemptions (e.g., newly developed drugs outside price control), a pattern that encourages development of novel drug technologies.
A student could infer that policy incentives for R&D make it more likely that advanced approaches like nanotechnology-based targeted delivery would be researched and developed domestically, and then check regulatory guidelines for such products.
Calls for an inter-ministerial group to boost R&D and for quicker clearance of new drug applications indicate institutional mechanisms exist to evaluate and potentially approve novel drug technologies.
One could use this to reason that if nanotech drug carriers are developed, there is a procedural pathway for their regulatory assessment and market entry; confirm by examining specific regulatory approval criteria.
The pharmaceutical industry has grown substantially (large production share and export orientation), showing infrastructure and expertise that can support development/manufacture of advanced formulations.
A student might combine this industry capacity with knowledge of nanomedicine manufacturing requirements to judge feasibility of producing targeted nanodrugs in the sector.
Discussion of solvents and traditional formulation methods highlights that drug delivery depends on formulation techniques—implying that new formulation technologies (e.g., nanoformulations) are part of the same conceptual space.
One could extend this by comparing standard formulation principles to nanocarrier approaches to see how formulation changes can enable targeted delivery.
The industry’s dependence on imported raw materials (APIs) shows a supply-chain constraint that could affect adoption or scale-up of specialized technologies.
A student could use this to temper expectations: even if nanotech enables targeted delivery technically, supply/dependency issues might affect implementation—check availability of required nano-grade materials.
