Nanoparticles Flashcards
What are nanoparticles?
Particles that are between 1 and 100 nanometres in size
What materials can nanoparticles be made from?
Metals, semi-conductors, or organic compounds
What are the possible structures of nanoparticles?
Fullerenes, tubes, or other shapes
What is the significance of the high surface area to volume ratio in nanoparticles?
Gives them enhanced reactivity
How do nanoparticles benefit medicine?
Can pass through cell membranes for targeted drug delivery
In what ways can nanoparticles be applied in catalysis?
To speed up chemical reactions. The large surface area allows a greater proportion of the reactant particles to come into contact with the catalyst.
What advantage do nanoparticles provide in terms of material strength?
Improve strength and flexibility without adding much weight
What are some uses of nanoparticles in medicine?
Targeted drug delivery, improved imaging, innovative therapies for diseases such as cancer
How are nanoparticles utilized in environmental science?
To remove pollutants from water and air
What role do nanoparticles play in the electronics industry?
Used for their ability to conduct electricity and create lightweight materials
What is a common application of nanoparticles in consumer products?
Used in sunscreens and cosmetics to block UV rays while being virtually invisible
What are potential risks associated with nanoparticles?
Could have toxic effects on human health and the environment
What specific risks do nanoparticles pose due to their size and reactivity?
Pose risks if inhaled, ingested, or come into contact with skin
