Droplet-based microfluidics

Definition

Droplet-based microfluidics refers to a technology that manipulates small volumes of fluids in the form of discrete droplets within microchannels. This approach allows for precise control over reaction conditions, enabling rapid and efficient analysis of biological samples, including viruses. By generating and handling thousands of droplets simultaneously, this method significantly enhances the capabilities for virus detection and characterization.
