Detection of cyan fluorescence in preclinical and clinical studies using fluorescence imaging. Standard (top panel) and fluorescence (bottom panel) images were captured of preclinical and clinical cases of cyan fluorescence from Pseudomonas aeruginosa (PA). Cyan fluorescence was detected 24 h after inoculating blood agar plates with PA (a), and 24 h after NCr mouse wounds were inoculated with PA (b). Cyan fluorescence has also been observed from chronic wounds positive for PA (c,d), confirmed by microbiological analysis (clinicaltrials.gov (accessed on 1 February 2021): NCT03540004). White arrows denote regions of cyan fluorescence.
