DAEJEON, South Korea, Nov. 22, 2023 — Until now, scientists have relied on fluorescence microscopy techniques to study intracellular cargo transport, a vital process to maintaining essential cellular functions. However, the effects of photobleaching and the visual isolation of cellular features from their environment limit the modality’s ability to glean information about the process and how it is conducted within the crowded cellular environment.
