(Bottom) Schematic of the inlet and outlet capillary tubes of the dynamic cell culture system. Media and NPs (when used) are drawn through the inlet and flow over HUVECs cultured on the capillary surface, as indicated by thick dashed lines, then returned to the reservoir in a closed-loop system. O2 and CO2 are allowed to diffuse through the top surface of the reservoir.
