Microfluidic control of nucleation and growth of calcite

The nucleation and growth of calcite is an important research in scientific and industrial field. Both the macroscopic and microscopic observation of calcite growth have been reported. Now, with the development of microfluidic device, we could focus the nucleation and growth of one single calcite. By changing the flow rate of fluid, the concentration of fluid is controlled. We introduced a new method to study calcite growth in situ and measured the growth rate of calcite in microfluidic channel.
