Abstract
A PEGylated quinoline-annulated porphyrin derivative was synthesized as in vivo photoacoustic tomography contrast agent. It possesses high solubility and stability in water and phosphate-buffered saline. No toxicity sign was observed in BALB/c mice. The dye demonstrates a 4-fold higher photoacoustic signal generation efficiency compared to fresh rat blood. Injection of the dye results in a significant enhancement of in vivo PAT images of murine tumors. Analysis of the mouse urine after injection revealed an unaltered renal filtration of the contrast agent.
