Droplet-based microfluidics

Definition

Droplet-based microfluidics refers to a technology that manipulates small volumes of liquids, forming discrete droplets that can be precisely controlled and analyzed. This technique enables the study of chemical reactions, biological processes, and material properties at a microscale by encapsulating samples within these droplets. By allowing for the manipulation of individual droplets, this approach enhances experimentation capabilities and facilitates high-throughput screening.
