摘要:
The present invention provides a method for maintaining heterogeneous concentrations of transitory target molecules in emulsion droplets by using one of a number of means to associate them to other, non-transitory molecules within the emulsion droplets contained in a microfluidic device. The present invention further provides a method for ensuring that the concentration and speciation of molecules will remain constant when stored in emulsion droplets. This results in emulsion droplets having heterogeneous concentrations of molecules, thereby improving the performance and applicability of droplet-based microfluidics.
