Speciation of selenium in yeast cells

Integrated microfluidic chip for selenium speciation

In this paper, researchers from the Whuan University in China present a new method for speciation of selenium in yeast cells.

Using on-chip magnetic solid phase extraction and high performance liquid chromatography (HPLC)-inductively plasma mass spectrometry (ICP-MS), Bin Hu and colleagues revealed that the amount of selenocysteine and selenomethionine in a single-enriched cell are in the order of picograms.
According to the authors, this new analytical method is sensitive, fast, low cost and easy to use.
