High-Speed Cell Holography Spots Beacons of Disease

By measuring physical aspects of a cell, researchers can identify signs of disease.

Duke University scientists have engineered a holographic system that can image and analyze tens of thousands of cells per minute to identify disease indicators.

Sample cells can be washed off the collector into a biocompatible solution and deposited into a microfluidic chip; the sample flows into channels under a line camera.

The camera reads the illuminated cells' topography and calculates their features, which when combined with data points and deep learning, can serve as disease-spotting markers.

The system differentiated between healthy and cancerous or carcinogen-exposed pre-cancerous cells with 98% to 99% accuracy.

Duke's Cindy Chen said, "The idea is that, by having this wealth of quantitative data, you can separate the cells better than if you were using one single metric."
