Figure 6

Effect of picolitre droplet printing technique on cell viability and activity. (a) The effect on the viability of printed K562 cells with different input signal voltages. (b) The printed k562 cells still have good propagation ability. The scale bar is 20 μm. The experiment was carried out in a bio-specific fume hood as a way to ensure sterility and prevent contamination.
