Campanile Tips (3 of 3) (image) DOE/Lawrence Berkeley National Laboratory Caption Using the campanile tip, Berkeley Lab researchers take "color" images with nanoscale resolution. A photovoltaic indium-phosphide nanowire is easy to see in a black-and-white electron micrograph (left) but chemical information has low resolution in a normal confocal micrograph (right). The campanile tip reveals both shape and chemistry of a nanowire (center).
