Question
Nanorods made of this metal are being investigated as potential phototherapy agents that give off heat in tissue when irradiated. For 10 points each:
[10m] Name this metal. The Turkevich method is used to synthesize nanoparticles of this metal, small-sized examples of which give off a vibrant pinkish-red color.
ANSWER: gold [or Au; accept gold nanorods; accept colloidal gold]
[10h] Gold is used as a sample stage in this technique for measuring ligand binding affinities and thickness of thin films. In this technique, a beam of light excites eponymous quasiparticles that propagate parallel to the sample sheet.
ANSWER: SPR [or surface plasmon resonance; prompt on plasmon resonance]
[10e] Nonconductive samples used in a form of this technique are coated with gold particles to allow interaction with an incoming electron beam. A sharp conducting tip images surfaces in the scanning tunneling form of this technique.
ANSWER: microscopy [accept word forms like microscope; accept scanning electron microscopy or scanning tunneling microscopy]
