Microfluidic Chip For High Efficiency Microinjection Of Caenorhabditis Elegans, Delaney Gray, Alex Hadsell, Jessica Talamantes

Bioengineering Senior Theses

The terrestrial nematode, Caenorhabditis elegans, is an invaluable model organism for the study of molecular and cellular processes due to their small size, rapid generation time, easy cultivation, and invariant cell number. Additionally, 40% of genes known to be associated with human disease have clear orthologs in the C. elegans genome. In C. elegans genetics research, microinjection of genetic material into the worms is critical. Although an established technique, manual microinjection is tedious, low-throughput, and requires an expert researcher. This thesis details a novel microfluidic device designed to perform high-throughput microinjection. This two-layer, PDMS-based chip integrates microfluidic elements to …
