Abstract
SummaryIn this study, we present a new application of the transmission electron microscopy dark field mode for cell imaging. We have applied this imaging mode to two types of cellular systems: human HeLa cells to analyze molecular membrane systems and HC11 mouse mammary cells containing lipid molecule droplets. We have also studied a third macromolecular system, copolymer nanoparticles for the characterization of core‐shell structures. We want to show the effective use of diffraction contrast, even on amorphous systems for increasing the image contrast and the signal/noise ratio. We discuss the TEM dark field advantages for the analysis of polymers and other macromolecular systems, including biological, systems compared to the bright field mode.
