Brown University Engineers Develop All-Electrical Cell Imaging Technique

Engineers at Brown University have developed an electrical imaging method to track cell migration without traditional optical microscopes. Published in the journal Lab on a Chip, the technique uses a microchip array of 1 million electrodes to monitor cells in a liquid nutrient solution.

By measuring changes in electrical capacitance as cells move across the chip, researchers can observe dynamics like cancer metastasis and division without damaging cells with fluorescent dyes. This approach avoids the potential behavioral disruption and DNA damage often associated with optical and fluorescence-based imaging technologies.
