Abstract
Growing evidence suggests that intravital flow–structure interactions are critical morphogens for normal embryonic development and disease progression, but fluid mechanical studies aimed at investigating these interactions have been limited in their ability to visualize and quantify fluid flow. In this study, we describe a protocol for injecting small (≤1.0 μm) tracer particles into fluid beds of the larval zebrafish to facilitate microscale fluid mechanical analyses. The microinjection apparatus and associated borosilicate pipette design, typically blunt-tipped with a 2–4 micron tip O.D., yielded highly linear (r2=0.99)
