This substance, which is imaged in photothermal optical microscopy, is mixed with silica or alumina to enhance signal in SHINERS, an extension of surface-enhanced Raman spectroscopy.
This substance, which is imaged in photothermal optical microscopy, is mixed with silica or alumina to enhance signal in SHINERS, an extension of surface-enhanced Raman spectroscopy. A method to produce this substance repeatedly adds a citrate reducing solution that additionally serves as a capping agent and was pioneered by Turkevich. This substance is conjugated to secondary antibodies in a stain used for (*) electron microscopy. The addition of SH-PEG to this substance results in the self-assembly of "sponge" structures. Citrate caps make this substance easier to functionalize as they are easily substituted for the desired thiol-substituted groups. The localized surface plasmon resonance this substance experiences results in its reddish-purple color. For 10 points, name this substance, typically a suspension of extremely small particles of the heaviest naturally occurring coinage metal.
