Abstract:
We demonstrated DNA droplets could be injected with an inkjet injector for microchannel array electrophoresis and attained high throughput analysis of biomolecules. This injection method greatly reduced both analysis time and sample amount, compared with a conventional microchip electrophoresis method, and allowed high parallelization of a microchannel array on a small substrate. Since we do not need to use complicated electric programs or microchannel design, our injection method should facilitate omics analyses and contribute to high performance clinical assays.
