Particle sorting is fundamental to biological and medical research, although existing methods are unable to sort large-sized particles via high-throughput sorting. In a new report, Y. Kasai and a research team in Japan, Germany and Poland presented a new on-chip sorting method based on traveling vortices generated by on-demand microjet flows. The method allowed high-throughput sorting using an activation system for fluorescent detection to sort 160 micrometer beads and purified fossil pollen from lake sediments. The method enhanced the achievement of chronologies of fossil pollen for paleoenvironmental records of sedimentary archives. The method has cross-disciplinary applications in genomics, metabolomics and regenerative medicine. It will open up new opportunities for pollen use in geochronology, paleoecology and paleoclimatology. The work is now published on Science Advances.
