Abstract

Devices and methods for implementing cell-based assays and long-term cell culture. The device and method are based on digital microfluidics (DMF) which is used to actuate nanoliter droplets of reagents and cells on a planar array of electrodes. DMF method is suitable for assaying and culturing both cells in suspension and cells grown on surface (adherent cells). This method is advantageous for cell culture and assays due to the automated manipulation of multiple reagents in addition to reduced reagent use and analysis time. No adverse effects of actuation by DMF were observed in assays for cell viability, proliferation, and biochemistry. These results suggest that DMF has great potential as a simple yet versatile analytical tool for implementing cell-based assays and cell culture on the microscale.
