Multiple choice

Consider the following statements:

  1. Nanotechnology is also called atomic engineering.
  2. Nanotechnology is useful in destroying tumors of cancer.

Which of the given statements is/are correct?

  1. Only (1)

  2. Only (2)

  3. Both (1) and (2)

  4. Neither (1) nor (2)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

(1) Nanotechnology is also called carbon engineering. (2) Yes, nanotechnology is useful in destroying tumors of cancer. A nanoshell of 100 nm diameter floating through the body will be able to get attached only to cancerous cells, which, upon excitation by a laser beam, will dissipate heat and destroy the tumor.

Multiple choice

Which of the following is a method of gene delivery using nanomaterials?

  1. Electroporation

  2. Impalefection

  3. Microinjection

  4. Biolistics

  5. Liposome mediated transfer
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Liposomes are able to interact with the negatively charged cell membrane more readily than uncharged liposomes, with the fusion between cationic liposome and the cell surface resulting in the delivery of the DNA directly across the plasma membrane.

Multiple choice

Which of the following abilities help(s) to redevelop the lost body part or the formation of the whole body from a body fragment?

  1. Restorative regeneration

  2. Repairative regeneration

  3. Both of the above

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Restorative regeneration is the specific biological process that allows organisms to regrow lost body parts or regenerate entire organisms from fragments. This differs from reparative regeneration, which only involves healing damaged tissues without complete replacement. Planaria and starfish are classic examples of organisms capable of restorative regeneration.

Multiple choice

What is/are the advantage(s) of using nanotechnology for medical applications?

  1. Nanodevices are less invasive and can be implanted inside the body.
  2. Biochemical reaction takes longer time at nanoscale, hence healing is complete.

  1. Only 1

  2. Only 2

  3. Both 1 and 2

  4. Neither 1 nor 2
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nanomedicine ranges from medical applications of nanomaterials to nanoelectronic biosensors and even possible future applications of molecular nanotechnology. A benefit of using nanoscale for medical technologies is that smaller devices are less invasive and can possibly be implanted inside the body.

Multiple choice

Directions: For this question, select the best of the answer choices given.

Although the new cochleae manufactured by Medotech will cost more than twice as much as the cochlear implants now in use, Medotech implants should still be cost-effective. Not only will surgery and recovery time be reduced, but Medotech cochlear replacements should last longer, thereby reducing the need for further hospital stays. Which of the following must be studied in order to evaluate the argument presented above?

  1. The amount of time a patient spends in surgery versus the amount of time spent recovering from surgery.

  2. The amount by which the cost of producing Medotech cochlear replacements has declined with the introduction of the new technique for producing them.

  3. The degree to which the use of Medotech cochlear replacements is likely to reduce the need for repeat surgery when compared with the use of the replacements now in use.

  4. The degree to which the use of Medotech replacements are more carefully manufactured than are the replacements now in use.

  5. The amount by which Medotech will drop in cost as the production procedures become standardized and applicable on a larger scale.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The best answer is (3). To evaluate the argument it must be determined whether these savings will compensate for the increased cost. Therefore, study of the expected reduction in the need for further hospital stays is needed.
