Characterization
of nucleation processes is essential to the development of strategies
to control crystallization in many industrial, atmospheric, biological,
and geological environments. An effective route to studying nucleation
processes is the use of large numbers of small, identical volumes,
where these minimize the effects of impurities that can dominate in
bulk solution and allow the stochastic nature of nucleation to be
considered. Here, we present a multilayered microfluidic device for
nucleation studies that can be used to carry out 10 000 simultaneous
reactions in identical microcavities, and 500 of them are used for
investigating nucleation kinetics. Unlike droplet-based systems, no
surfactants are required, and the presence of an integrated water
reservoir prevents water loss, allowing studies to be performed for
long durations. This device was used to study the nucleation of calcium
carbonate in the presence and absence of magnesium ions. Two distinct
nucleation rates of 286 cm–3 s–1 and 12.6 cm–3 s–1 were observed
in the absence of magnesium, where the rapid rate likely derives from
microcavities containing impurities. The nucleation rate was then
significantly reduced in the presence of magnesium ions, and the profile
was more complex. This device is therefore an ideal platform for studying
slow nucleation processes in surfactant-free environments.
