Question and Answer

       PRESENTATION HIGHLIGHTS:

  • [00:00:00] Does IR measurement depend on the type of samples such as soft polymers or heart polymers?
  • [00:01:25] What is the rough measurement time for REV AFM-IR?
  • [00:02:38] What types of probes are used for these measurements?
  • [00:04:23] Can we look at the same orders and properties in AFM-IR while simultaneously looking at the monolayer density through other channels such as phase contrast or mechanics?
  • [00:06:38] Does the IR amplitude change depending on the contact resonance frequency?
  • [00:08:45] What is the difference between the adhesion mapping and what we get through REV AFM-IR and peakforce Tapping?
