Darkfield, ultrasound and photoacoustic images (λ = 532 nm and 680 nm) of control, targeted and non-targeted tissue phantoms. The darkfield images measure 440 μm by 340 μm field of view. The ultrasound and optoacoustic images measure 2 mm by 1.67 mm. The targeted EGFR cells show high photoacoustic signal due to the plasmon resonance coupling resulting from clustering gold nanoparticles. Reproduced from Mallidi S, Larson T, Aaron J, et al.
