They use capillary action, which is a fundamental principle of microfluidics, to draw ink from the reservoir into the nib of the pen. The nib of a fountain pen is made up of a series of tiny ...

Droplet creation is a crucial but challenging subject in microfluidics. Depending on the application, the objective is to produce droplets of a particular size. Two immiscible phases are used in ...

At Texas A&M University, one research lab is changing the game of droplet microfluidics, a technique that involves conducting ...
