Figure 2. Characterizations of the JNPs. (A) UV/Vis spectra of Au/PAA, Au/PAA-ALA, and FA-Au/PAA-ALA JNPs (insets show UV/Vis spectra of the citrate-Au NPs and 5-ALA), (B) the average hydrodynamic size of FA-Au/PAA-ALA JNPs using DLS, (C) TEM images of (a) citrate-Au NPs and (b) Au/PAA JNPs, (D) FTIR spectra of 5-ALA, Au/PAA, Au/PAA-ALA, and FA-Au/PAA-ALA JNPs, (E) photostability of the final actively targeted FA-Au/PAA-ALA JNPs in PBS over three weeks.
