Abstract
Coherent confocal light absorption and scattering spectroscopic (C-CLASS) microscopy, which extends the principles of light scattering spectroscopy to subcellular imaging, can be used to reveal biological structures well beyond the diffraction limit. Here we show that high-resolution C-CLASS microscopy can be used to detect nanoscale changes in chromatin structure. Unlike most methods for chromatin monitoring, C-CLASS microscopy can be used label-free in live cells. Live differentiating hiPSC organoids were measured over the space of sixteen days and characteristic chromatin changes were observed.
