Final answer:
Nanotechnology has a wide range of applications, including medicine, and several options mentioned are examples of nanomaterial applications. However, sunscreens and fuel cells are not applications of nanomaterials.
Step-by-step explanation:
Nanotechnology has a wide range of applications in various fields, including medicine. Three of the options mentioned are examples of applications of nanomaterials:
- TV and computer monitors - Nanomaterials are used in the manufacturing of display screens to enhance image quality.
- Cardiology - Nanomaterials are used for drug delivery systems and diagnostic imaging in cardiology.
- Magnetic Resonance Imaging (MRI) - Nanomaterials are used as contrast agents in MRI to improve image quality.
Therefore, the option that is not an application of nanomaterials is Sunscreens and fuel cells.
