Capture, Confine, Characterize: High‐Throughput Dielectrophoresis‐Based Single‐Cell Microfluidics Platform to Analyze Mammalian and Yeast Cells Using Raman Spectroscopy

Small, Volume 22, Issue 31, 2 June 2026.
Traditional single‐cell analysis lacks the capacity for real‐time monitoring. This study presents Microfluidic dielectrophoretic Arresting System (MiDAS), a microelectrofluidic platform using dielectrophoresis for single‐cell and droplet trapping. MiDAS immobilizes diverse samples (cells, beads, droplets) for optical imaging and Raman spectroscopy. Its
