Holotomography has emerged as a helpful tool for imaging live specimens without additional pre-treatment, such as fixation, fluorescence labeling, and excitation. It can achieve long-term three-dimensional observations of live specimens for weeks without cellular damage caused by photoactivation. The high resolution (under 150 nm lateral) achieved through synthetic numerical aperture provides sufficient spatial information to distinguish various subcellular compartments such as nuclei, nucleoli, mitochondria, and lipid droplets. Furthermore, analysis of the measured individual cell data can elucidate the temporal 3D volumetric dynamics with the dry mass information. This episode presents the latest development of a low-coherence holotomography imaging system, HT-X1, and its numerous applications to different types of biological specimens, ranging from unicellular organisms to multicellular specimens. Plus, learn how to combine holotomography with downstream molecular analysis, such as cell biology, immunology, microbiology, material science, and in vitro diagnosis.Watch the full presentation here: https://events.bitesizebio.com/label-free-3d-live-cell-imaging-and/joinBrowse all episodes of the Listen In Series here: https://listen-in.bitesizebio.com/
