Page "Microfluidics" Paragraph 64

The ability to create precise and carefully controlled chemoattractant gradients makes microfluidics the ideal tool to study motility, chemotaxis and the ability to evolve / develop resistance to antibiotics in small populations of microorganisms and in a short period of time.

These microorganisms including bacteria and the broad range of organisms that form the marine microbial loop, responsible for regulating much of the oceans ' biogeochemistry.
