InactiveUS20160051353A1Efficient deliveryCompounds screening/testingDiagnostics using lightTemplate matchingPressure.drive
Automatic system for efficient delivery of biologics into target organs of zebrafish larvae for high-throughput in vivo screening. The system includes a reservoir containing zebrafish larvae immersed in a hydrogel in its liquid state. A microfluidic component removes a droplet of the hydrogel having a single zebrafish larva contained therein and deposits the droplet on a surface for receiving an array of hydrogel droplets. Structure or substances is provided for inducing the larva to assume a dorsal or lateral orientation within the droplet. A cooler cools the surface to solidify the hydrogel droplets thereby to immobilize the larvae for observation by an optical arrangement that identifies target organs in each larva using an image template-matching algorithm. A pressure driven microinjection needle injects biologics into the target organ of the zebrafish larva for screening studies.
