3D pHe Mapping (IMAGE) Kanazawa University Caption High-resolution 3D pHe mapping of living melanoma cells with feedback-controlled double-barrel SICM-pH nanoprobe. The 3D SICM topographical images (left column) and 3D pHe distributions (right column) of low-buffered living melanoma A375M obtained simultaneously by a single SICM scanning, which demonstrated a highly variegated distribution pattern of pHe. Scale bars represent 20 μm. Courtesy of Nature Communications Credit Kanazawa University Usage Restrictions The image may only be used with appropriate caption and credit.
