Kind: research · Impact: low

## In brief

- A chip identifies cells by their electrical signature rather than by labels.
- After identification, cells are separated using a precisely aimed sound wave.
- The approach aims to avoid the stress and behavior changes caused by extrinsic labeling used in methods like fluorescence-activated cell sorting.

## Why it matters

Label-free sorting that avoids stressing cells could make cell-based biomedical assays more reliable and less disruptive to the cells being studied.
