PA-US imaging of AuNPs and AuNS in gelatin phantoms. PA images, PA-US spectra and PA intensities at 710 nm of (a, b, c) AuNPs, (d, e, f) AuNS HEPES, (g, h, i) AuNS EPPS, and (j, k, l) AuNS MOPS at different gold concentrations (from 0 to 200 µM). Values in columns represent mean ± standard deviation of three different batches of nanoconstructs
