The robotic pill was incubated for one hour in a solution containing E. coli at a starting OD600 of 1.48 ± 0.04 (n=3), indicating high turbidity and bacteria quantity. After incubation, the absorbent material inside the robotic pill was transferred to a solution containing growth media and was measured every hour to evaluate its growth (Figure 3e). A control study was performed incubating a robotic pill in growth media without bacteria to test for contamination. After 6 hours, the control robotic pill presented a background OD600 of 0.05 ± 0.003 when compared to 0.67 ± 0.03 for the pill incubated with bacteria, illustrating the ability for the pill collector to trap and retain living bacteria (Figure 3f).
