  • Researchers have elucidated several methods to tell live and dead cells apart, and one popular approach is the “dye exclusion test (DET)” using synthetic dyes.
  • In conventional DET, a dye such as trypan blue or methylene blue selectively permeates and stains dead cells, distinguishing them from live cells.
  • This applicability of MP to completely different kinds of cells — breast cancer, Euglena, and Paramecium — has made Dr Yamashita very optimistic about its potential.
