AFM QUIZ

What is the purpose of AFM

• To calculate the enthalpy of a substance

• To obtain advanced topographical information about a substance

• To test the boiling point of a substance

• To measure the fluorescence of a substance

What component is NOT a part of AFM

• Nanoprobe

• Cantilever

• Laser

• Tungsten Lamp

What is the rough diameter of the nanoprobe's tip?

• 1-2nm

• 10-20nm

• 10-20mm

What solvent is NECESSARY for AFM?

• hexane

• water

• acetonitrile

• No solvent necessary

What is the laser deflected off of to be directed toward the detector?

• It is deflected off of the probe tip

• It is deflected off of the sample

• It is deflected off of the top of the cantilever surface

• Deflection never happens

Up to how much magnification does AFM provide for sample analysis?

• up to x1000 magnification

• up to x10,000 magnification

• up to x500,000 magnification

• up to x1,000,000 magnification

In what field of science is AFM not used in?

• nanotechnology

• biology

• material analysis (like metals, semiconductors, and polymers)

• AFM is used in all of these fields!

What is true of the two modes of AFM?

• Non-contact mode uses bouncing oscillation to interact with the sample

• Contact mode uses bouncing oscillation to interact with the sample

• Contact mode actually never touches the sample

• Non-contact mode is always touching the sample during data collection
