PAI of breast and ovarian cancer cells. A Cross-sectional PA images at 890 nm excitation overlaid B-mode ultrasound of gelatin phantoms containing inclusions of breast cancer cells MDA-MB-468, MDA-MB-231, and MDA-MB-435 labeled with either EGFR-targeted (ICGJ@PEI Ps-Ab) or nontargeted (ICGJ@PEI Ps) polymersomes and B corresponding PA spectra that are based on volumetric PA signal analyses. C Cross-sectional PA images overlaid B-mode ultrasound of gelatin phantoms containing inclusions of ovarian cancer cells SKOV3 and A2780 labeled with either EGFR-targeted (ICGJ@PEI Ps-Ab) or nontargeted (ICGJ@PEI Ps) polymersomes and and B corresponding PA spectra that are based on volumetric PA signal analyses.(each value shows mean ± SD based on n = 3 samples). The image was reproduced from article published by Changalvaie, Johnston and co-workers in ACS Applied Materials and Interfaces journal in the year 2019 [104]
