Figure 3

Fluorescently measured single enzyme reaction in picoliter volume reactors. Devices that have undergone 7 min PECVD were filled with 0.25 U/mL horseradish peroxidase (HRP) and exposed to 2.5μM hydrogen peroxide (H2O2) using a constant flow rate of 10 μL/hr. Representative fluorescent micrographs of the cell mimic devices taken a different time points are shown. Error bars representing +/- one standard deviation of 3 individual devices on 3 separate chips are shown at 20 seconds intervals for clarity.
