# Artist’s rendering of an organ-on-a-chip device

## Appears In

                        - NIST-Led Working Group Developing Standards for Organ-on-a-Chip Research
                        - Physical Measurement Laboratory

Artist’s rendering of an organ-on-a-chip device used to study cancer cells (red) and endothelial cells (green), a type of tissue that lines the interior surface of blood vessels. This close-up shows two overlapping channels with a thin semi-permeable membrane between them. Electrodes are used to trap cells in each channel, allowing researchers to observe cell-to-cell interactions between the two types of cells on the chip.
