Abstract:
:Understanding metabolism in live microalgae is crucial for efficient biomaterial engineering, but conventional methods fail to evaluate heterogeneous populations of motile microalgae due to the labelling requirements and limited imaging speeds. Here, we demonstrate label-free video-rate metabolite imaging of live Euglena gracilis and statistical analysis of intracellular metabolite distributions under different culture conditions. Our approach provides further insights into understanding microalgal heterogeneity, optimizing culture methods and screening mutant microalgae.

杂志文章abstract::Zika virus (ZIKV) is associated with neonatal microcephaly and Guillain-Barré syndrome1,2. While progress has been made in understanding the causal link between ZIKV infection and microcephaly3-9, the life cycle and pathogenesis of ZIKV are less well understood. In particular, there are conflicting reports on the role...
