The newest INNODERM publication has been published in Nature Communications by consortium partner TUM. In the publication, the authors present a homogentisic acid-derived pigment (HDP) for biocompatible intracellular labeling of macrophages with strong optoacoustic contrast efficient enough to resolve single cells with RSOM against a strong blood background. This work expands the sparse palette of macrophage labels for in vivo optoacoustic imaging and facilitate research on macrophage functionality and behavior.
