Cell culture is typically performed in Petri dishes, where a few million cells growing together, or in microwell plates with thousands of cells in each compartment. When the throughput of each experiment, especially of screening based assays, is increased, even using microliter solution per well will cost a considerable amount of cells and reagents. We took a rational approach to reduce the volume of each cell culture chamber. We designed and fabricated a poly(dimethylsiloxane) based liquid pipette chip to deliver and transfer nanoliter (50 nL to 500 nL) samples and reagents with high accuracy and robustness. A few tens to a few hundreds of cells can be successfully seeded, transferred, passaged, transfected, and stimulated by drugs on a microwell chip using this pipette chip automatically. We have used this system to test the cell growth dynamically, observed the correlation between the culture conditions and cell viabilities, and quantitatively evaluated cell apoptosis induced by cis-diammineplatinum(II) dichloride (Cisplatin). This system shows great potential to facilitate large-scale screening and high-throughput cell-array based bioassays with the volume of each individual cell colony at nanoliter level.
