Basics
What scale does nanotechnology focus on?
Nanoscale
What size range is considered the nanoscale?
1 to 100 nanometers
How is nanotechnology used in sunscreen?
effective UV light-absorbing
What is drug delivery?
Delivers drugs directly to diseased cells, protecting healthy cells and reducing side effects.
What does nanotechnology manipulate?
Materials
How does size affect the color of quantum dots?
Smaller dots emit shorter wavelengths, like blue, larger dots emit longer wavelengths, like red
How are nanoparticles used to protect your skin?
Creates a physical barrier on the surface of skin
At what stage do nanosensors detect diseases?
Nanosensors detect diseases early, enabling timely intervention and better outcomes.
What is nanotechnology?
The study and use of tiny particles, typically at the scale of atoms and molecules, to create new materials and devices with unique properties.
Why are nanoparticles better catalysts than bulk materials?
They have a larger surface area, exposing more active sites.
What are the disadvantages of nanoparticles in cosmetics?
can damage intact skin.
What is photothermal therapy?
This cancer treatment uses nanoparticles to heat and destroy cancer cells with less harm to healthy tissues.
