Synthesis and application of MoS2-ICG. Using ICG to covalently modify MoS2 nanosheets, this covalent connection makes the composite have extremely high optical absorption capacity in a wide near-infrared band, and photoacoustic imaging can achieve lower background noise and greater penetration depth at longer wavelengths. The complex was applied to in vivo photoacoustic imaging of in situ glioma in mice, demonstrating the high sensitivity for visualization of deep glioma.
