In the realm of life sciences, confocal fluorescence microscopy (CFM) is celebrated for its high-resolution cellular imaging capabilities. However, the necessity for fluorescent staining in CFM can lead to photobleaching and phototoxicity, which may harm the cells being studied. To address these limitations, a research team at POSTECH has developed a novel imaging method that utilizes explainable deep learning (XDL) to enhance mid-infrared photoacoustic microscopy (MIR-PAM), allowing for label-free imaging while preserving cell integrity.
The innovative approach involves a two-phase imaging process that first enhances the resolution of MIR-PAM images and then creates virtually stained images without the use of fluorescent dyes. This technology not only improves the visualization of intricate cellular structures but also maintains the health of live cells, making it a significant advancement for biological research. The potential applications of this method in live-cell analysis and disease model studies are vast, promising to revolutionize how cellular imaging is conducted.
