Researchers from St. Andrews University in the UK used a micro blue OLED display to active individual live cells from a human embryonic kidney cell line that were tweaked to produce a light-sensitive protein.

The researchers say that this ability to use OLEDs to activate individual cells may enable cell-specific optogenetic control in cultured neuronal networks, brain slices, and other biomedical research applications. They say that OLEDs are an "ideal platform technology for investigating and controlling biological processes with single cell resolution".
