Morphology, Aggregation Properties, Cytocompatibility, and Anti-Inflammatory Potential of Citrate-Stabilized AuNPs Prepared by Modular Ultrasonic Spray Pyrolysis

Figure 4

Surface Plasmon Resonance properties and hydrodynamic size distribution of AuNPs in citrate solution and complete RPMI medium. (a) The UV-vis spectra of AuNPs are shown, dispersed either in citrate-solution or in complete RPMI medium for 2 h or 24 h. (b) The hydrodynamic size of AuNPs was measured either in citrate buffer or in complete RPMI medium by Dynamic Light Scattering.
