Colored Water Shows How Liquid Wicks along Tiny Channels Formed in Paper Using a Laser.

Caption

Colored water is used to show how liquid wicks along tiny channels formed in paper using a laser, in research to develop a new technology for medical diagnostics and chemical analysis. Silica microparticles were deposited on patterned areas, allowing liquid to diffuse from one end of a channel to the other.
