During the design stage, we developed a low-cost, high-resolution polymer microfabrication technique termed laser stenciling.

When comparing transfection efficiency for our electro-sonoporation method to that of sonoporation or microelectroporation alone, we observed single batch improvements up to 20 percent and 17 percent, respectively. The average improvement in efficiency was approximately 15 percent greater than achieved with sonoporation and 10 percent greater than that of electroporation. Importantly, there was little difference in short term cell viability between the three methods (maintained at > 90 percent). The average transfection efficiency for electro-sonoporation was 81.25 percent and cell viability was 91.56 percent.
