Question 2 of 5
2. Question
Quantum dots (QDs) are man-made nanoscale crystals that can transport electrons. Potential applications of quantum dots include
- Single-electron transistors
- LEDs
- Medical Imaging
- Solar Cells
- Cell Biology Research
Select the correct answer code:
Correct
Solution: d)
Quantum dots (QDs) are semiconductor particles a few nanometres in size, having optical and electronic properties that differ from larger particles due to quantum mechanics.
When the quantum dots are illuminated by UV light, an electron in the quantum dot can be excited to a state of higher energy.
Potential applications of quantum dots include single-electron transistors, solar cells, LEDs, lasers, single-photon sources, second-harmonic generation, quantum computing, cell biology research, and medical imaging. Their small size allows for some QDs to be suspended in solution, which may lead to use in inkjet printing and spin-coating. They have been used in Langmuir-Blodgett thin-films. These processing techniques result in less expensive and less time-consuming methods of semiconductor fabrication.

Question 4 of 5
4. Question
Consider the following statements regarding Gold nanoparticles (GNPs).
- GNPs have lower solar radiation absorbing ability than the conventional bulk gold.
- They are useful in the electronics industry.
- They are capable of transferring various drugs made out of peptides, proteins, plasmid DNAs to target diseased cells of the human body.
Which of the above statements is/are correct?
Correct
Solution: c)
Nanoparticles (NPs) have wide variety of potential applications in the fields of biomedical, optical and electronics research. Metallic NPs have been efficiently exploited for biomedical applications and among them GNPs are found to be effective in biomedical research.
NPs are those materials that are at least one dimension smaller than 100 nanometres.
GNPs are found to have greater solar radiation absorbing ability than the conventional bulk gold, which makes them a better candidate for use in the photovoltaic cell manufacturing industry.
As nano-carriers, GNPs are capable of transferring various drugs made out of peptides, proteins, plasmid DNAs, small interfering RNAs, and chemotherapeutic agents to target diseased cells of the human body.
GNPs are also found to be useful in the electronics industry.

Question 5 of 5
5. Question
Consider the following statements regarding carbon nanotubes.
- Carbon nanotubes have higher strength than steel, but also weigh significantly more.
- They can be used as a container for transporting a drug in the body.
- They can conduct heat and electricity better than copper.
Which of the above statements is/are correct?
Correct
Solution: b)
Carbon nanotube is a tube-shaped material, made of carbon, having a diameter measuring on the nanometre scale.
Researchers have developed thin Carbon Nanotube (CNT) textiles that exhibit high electrical conductivity and a level of toughness about 50 times higher than copper films, currently being used in electronics.
CNTs are at least 100 times stronger than steel, but only one-sixth as heavy, so nanotube fibres could strengthen almost any material.
