Cell Printing Experimentation
From Course Wiki
Once cartridge experimentation was completed, the next step was to try the device on cells themselves.
For cell solution, I used RFP-expressing and GFP-expressing E. coli, grown in L-broth to an approximate density of 10^8 cells/mL. This concentration equates to approximately 6 cells/droplet.
Experiment 1: Basic printing
Key Question Can cells be seen after the solution is printed?
Design The experimental design for this was quite simple--load the black ink cartridge with 0.5 mL of RFP E. coli and print onto a microscope slide.
Result The cells did in fact print and they could be visualized in the defined pattern
