Contrast agents are attracting a great deal of attention in photoacoustic imaging. Here we introduce an exogenous contrast agent that provides high photoacoustic signal amplitude at the near-infrared wavelength. Our agents consist of Indocyanine green (ICG) and phospholipid–polyethylene glycol (PL–PEG), entitled ICG–PL–PEG nanoparticles. These nanoparticles have overcome numerous limitations of ICG, such as poor aqueous stability, concentration-dependent aggregation and lack of target specificity. ICG–PL–PEG nanoparticles are biocompatible and relatively nontoxic. All the components of ICG–PL–PEG nanoparticles have been approved for human use. Upon pulsed laser irradiation, the nanoparticles are more efficient in producing photoacoustic waves than ICG alone. The results showed that ICG–PL–PEG nanoparticles act as good contrast agents for photoacoustic imaging. These unique ICG–PL–PEG nanoparticles have great potential in clinical applications.

Resistance Prediction

Studies have shown that a higher GSH level is related to more drug-resistant and invasiveness of a tumor. However, it is a great challenge to accurately imaging the GSH level in vivo, for its imaging intensity will interfered by different accumulation of probes in the tumor. Thus, we hypothesized ratiometric photoacoustic imaging that can be used to predict the drug-resistant and invasiveness of tumors by accurate GSH level imaging. In this study, we synthesized MnO2/Indocyanine Green (MnO2/ICG). It can be used as ratiometric photoacoustic (PA) imaging probe, for its absorption at 780 nm (Ab780) can be decreased and 680 nm (Ab680) remain unchanged upon GSH reduction. And our results confirmed that a lower PA absorption ratio (Ab780/Ab680) corresponded to a higher GSH level of the tumor. Besides, the near-infrared fluorescence (FI) imaging was used as an assistant, for it can be quenched upon GSH. Therefore, MnO2/ICG can predict the tumor invasiveness and drug resistance by imaging the GSH level. This study provides reference to predict the prognosis of tumors by imaging the metabolic biomarker of tumors.
