PA-US imaging of functionalized AuNPs and AuNS in gelatin phantoms. PA-US images, PA spectra and PA intensities at 710 nm of functionalized (a, b, c) AuNPs, (d, e, f) AuNS HEPES, (g, h, i) AuNS EPPS and (j, k, l) AuNS MOPS at gold concentrations of 200 µM. (****) indicate groups that are significantly different with p < 0.0001 (one-way ANOVA). Values in columns represent mean ± standard deviation of three different batches of nanoconstructs
