SPA imaging of different agents embedded into polyacrylamide inclusion located inside an agarose gel: (a) NEB-GNS, (b) NEB-GNS filtered, (c) GNS-12 nm with the same amount of gold as NEB-GNS and (d) molecular dye IR-783 nm. The reference magnitude (0 dB) corresponds to the maximum of the SPA image. The laser fluence was 5.2 mJ/cm2 and the acoustic peak negative pressure measured at z = 35 mm was 1.6 MPa (wide-beam focusing at 60 mm).
