Digital holographic microscopy complements mass spectrometry for label-free quantification of nanoparticles within single cells
We combined laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) with volume measurement by digital holographic microscopy (DHM) to determine the concentration of CeO2 nanoparticles in single lung epithelial cells.
