    22nd, The Journal of Communications-Physics published a new technique for photo-acoustic imaging
    . Jan Laufer and colleagues from the University of Harley-Wittenberg in Germany used a method of photosensitive pigment reporting protein (AGP1) and dual wavelength interwoven image acquisition based on reversible light conversion to obtain differential images with clear report-specific contrasts.
    imaging provides high-resolution images of gene-labeled cells by reaching depths that optical microscopes cannot reach. In contrast to detecting reported genes such as fluorescent proteins and natural pigments, multi-wavelength imaging and spectral separation techniques are generally used, but these methods still present technical challenges due to the large amount of computation required.
    longitudinal tracking study, the authors obtained complete 3D images of tumors formed by lymphocytic cells expressing AGP 1 in deep tissues of the body using photo-acoustic imaging.
    this method will become a new and powerful tool for studying cells and genetic processes, and the experiment is simple to operate and can be widely used on existing optical and acoustic imaging platforms. (Source: Science.com)
