Characterization of Multispiked Gold Nanoparticles. a) The absorbance spectra of gold nanoparticles obtained by gold reduced with ascorbic acid, pHLIP®, and PEG in the absence and presence of bicelles of different asymmetries. b) The representative TEM image of pHLIP® and PEG coated multispiked gold nanoparticles obtained at 12,000× magnification. The size histograms of the metallic core of pHLIP® and PEG coated nanoparticles is shown in Supplementary Fig. S2b. c) The change in temperature over time measured in solutions containing pHLIP® and PEG coated spiked gold nanoparticles of different concentrations irradiated by an 805 nm laser.
