Dynamic follow up and analysis of isolated single cells that display non-adhering behavior is hinderedby the fact that they float in the suspension medium and thus requires the implementation of systemsthat physically entrap the cells for successful analysis. We describe the potential of digital microfluidic(DMF) chip technology for conducting analysis of cells in suspension at the single cell resolution. Morespecifically, we demonstrate the use of DMF technology for the analysis of a group of single individualprotoplasts from Arabidopsis thaliana plants that are labeled with magnetic particles and are immobilizedon the DMF chip by magnetic forces. By transporting droplets with different osmotic conditions to thesite where the cells are trapped, we challenge the cells and monitor their responses dynamically witha camera. The use of DMF technology for performing water potential measurements has the followingadvantages: (i) solid particles such as cells and magnetic beads are manipulated on the chip without therisk of clogging channels, (ii) low shear stress during droplet unit operations like mixing and transportthat characterize DMF are particularly suited for analysis of delicate cells types that lack cell walls such asprotoplasts, (iii) the throughput of the analysis is strongly increased as multiple protoplasts are analyzedsimultaneously, in contrast with the traditional methods that can handle and challenge only one cellat a time. We show that the DMF analysis platform is effective in creating the steep osmotic gradientsrequired for calculation of water permeability coefficients (P) as the values found are comparable withpreviously reported ones thus validating the suitability of the technology for such studies. This workillustrates a proof of concept for the applicability of DMF as an unparalleled and promising system forimplementing single cells studies on non-adhering cells in an automated way.
