SF carried out the comparative analysis presented in this work and elaborated on the proposed Monday-to-Friday schedule. SF and FF organized the protocol sections and wrote the paper, with ... WebTrypan blue evoked no acute toxicity, but it was chronically cytotoxic at all tested concentrations. Conclusions: Trypan blue, being more water-soluble than ICG, is probably retained to the least degree. This circumstance is fortunate given that trypan blue exhibits a chronic cytotoxicity comparable to ICG at all clinically relevant concentrations.
