Question 9

What is the significance of fluorescence spectroscopy in studying lipid bilayers?

Answer 9

It allows for monitoring the motions of molecules within a lipid bilayer by detecting re-emitted fluorescent light.

Question 10

What is the role of tryptophan and tyrosine in fluorescence spectroscopy?

Answer 10

Their side chains have intrinsic fluorescence, providing information about the protein portion of the membrane.

Question 11

What does ‘PSF’ stand for in fluorescence spectroscopy?

Answer 11

‘PSF’ stands for point-spread function, which is the error of estimate in localization of fluorophores.

Question 12

What technologies are used in drug delivery?

Answer 12

Injections, topical application to the skin, and implants.

Question 13

How do amphipathic molecules like fatty acids contribute to drug delivery?

Answer 13

They can form micelles, which package nonpolar substances with nonpolar tails sequestered from water.
