Structural engineering of silver nanoparticles for enhanced photoacoustic imaging.

ABSTRACT: Photoacoustic (PA) imaging is a diagnostic tool widely explored in (pre)clinical settings, as it combines the strengths of optical and ultrasound imaging, resulting in high contrast resolution and deep tissue penetration. Although PA imaging can directly visualize some endogenous molecules (e.g. deoxygenated and oxygenated hemoglobin), most of its applications require the administration of external probes, including organic dyes and inorganic nanoparticles. Despite being historically used for antimicrobial and wound healing applications, silver nanoparticles (AgNPs) possess clear merits for PA imaging, including tunable optical properties, high-quality localized surface plasmon (LSP) resonances, strong photothermal conversions, and photostability. In this study, we explored new PA imaging
