Optofluidic lab-on-a-chip for rapid algae population screening

Yves Bellouard

The rapid identification of algae species is not only of practical importance when monitoring unwanted adverse effects such as eutrophication, but also when assessing the water quality of watersheds. Here, we demonstrate a lab-on-a-chip that functions as a ...
