    • 2 μL/min) injected the precursor plug into the chip, after which a second ODE pump optionally diluted the plug before it entered the main reaction channel. The precursor plug reacted to form CdSe nanocrystals as it flowed continuously through the reaction channel, which was heated from below using a silicone heater. Typical reaction temperatures of 180 ± 0.5°C were measured by embedding a thermocouple into a hole drilled to microchannel depth. After a typical reaction time of 300 s, a third ODE syringe pump was used to dilute the nanocrystal solution and pump it into an external fused silica capillary flow cell, where fluorescence spectra (370 nm excitation) were measured using a fiber optic CCD spectrometer approximately 110 s after the nanocrystals exited the heated reaction channel.

    • Characteristic diffusion times were calculated by assuming precursor complex Stokes radii of 1 nm and using a 1:1 precursor/ODE flow ratio with total flow rate of 3 μL/min.
