Fig. 6: The in vivo photoacoustic (PA.) imaging of BALB/c mouse using ESi5-S agg.
From: A stable and biocompatible shortwave infrared nanoribbon for dual-channel in vivo imaging
The concentration (a) and laser intensity (b) dependent photothermal property of ESi5-S agg in PBS. c The calculation of the photothermal conversion efficiency of ESi5-S agg (30 μM) under continuous 1064 nm laser (1000 mW•cm−2) irradiation. d Photothermal stability of ESi5-S agg (30 μM) in PBS and IR-1061 (30 μM) in PBS under 1064 nm laser (1000 mW•cm−2) irradiation. e The photoacoustic intensity of the ESi5-S agg and IR-1061 in PBS excited by 1064 nm laser (n = 3, Data are presented as mean values ± SD). Photoacoustic imaging of BALB/c mice acquired (f) without ESi5-S agg and (g) 180 min post injection of ESi5-S agg (2.5 mg/kg in PBS). h, i Line intensities of the highlighted ROIs of the images of vertebra. Scale bar: 1 mm.
