The assay can be utilized to study feeding and foraging-related behaviors, as well as the underlying neuronal mechanisms. Bioengineering Simple Microfluidic Devices for in vivo Imaging of C. elegans, Drosophila and Zebrafish Sudip Mondal1, Shikha Ahlawat1, Sandhya P. Koushika1,2 1Neurobiology, NCBS-TIFR, 2Department of Biological Sciences, TIFR A simple microfluidic device has been developed to perform anesthetic free in vivo imaging of C. elegans, intact Drosophila larvae and zebrafish larvae. The device utilizes a deformable PDMS membrane to immobilize these model organisms in order to perform time lapse imaging of numerous processes such as heart beat, cell division and sub-cellular neuronal transport. We demonstrate the use of this device and show examples of different types of data collected from different model systems.
