Microarrays of OLEDs are used to ­optically control the locomotion of individual cells in real time. Close contact (<2 μm) between OLEDs and the aqueous cell culture medium is facilitated by high-performance thin-film encapsulation. This work paves the way for using OLED light sources to control and study neuronal activity and cell signaling with extreme spatial and temporal resolution.
