Laser-based Photoacoustic Method Provides Subcellular Insights

Facebook Twitter LinkedIn Email Comments
City University of Hong Kong researchers developed a multiwavelength optical resolution photoacoustic microscopy (OR-PAM) system based on a single laser source. The system enables simultaneous multicontrast imaging of hemoglobin concentration, blood flow speed, blood oxygen saturation, and lymphatic concentration. Information, at the level the new system is able deliver, provides subcellular insights useful for the study of disease models, such as in cancer research. Photoacoustic imaging works from the platform of the intrinsic absorption properties of the targeted biological tissue....Read full article
