Question 1.
What happens to the color of gold nanoparticles if you change their size?
Show hintHide hint
Think about how size influences absorption and scattering.
Question 2.
What is meant by light confinement?
Show hintHide hint
Consider the implications or benefits of confining light.
3Question 3.
What is size-dependent resonance?
- A phenomenon where light is absorbed equally by all particle sizes
- A property where the light interaction changes according to nanoparticle size
- None of the above
Show hintHide hint
Think about how smaller particles interact differently than larger ones.
4Question 4.
True or False: Light confinement can enhance electric fields.
- True
- False
Show hintHide hint
Consider the benefits of increasing field strength.
Question 5.
Consider a set of gold nanoparticles of varying sizes. Predict how their colors will differ when illuminated with white light, and explain why this occurs.
Show hintHide hint
Reflect on how the size influences interaction with light.
Question 6.
Design an experiment using nano-optical tweezers to manipulate small biological samples. What variables must be controlled to ensure accurate results?
Show hintHide hint
Consider how these factors affect light interactions and precision.
