Lensless imaging method enables long-term monitoring of living cells without staining

What happened

In a study led by Tampere University, researchers have developed a new lensless imaging method that produces precise quantitative data on living cells from a single image. The compact system can be placed inside a standard cell-culture incubator, allowing living cells to be monitored continuously for hours or even days without staining or other labels. The research is published in the journal Applied Physics Letters.
