Findings from Inha University Provides New Data on Caenorhabditis elegans

May 20, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Caenorhabditis elegans have been published. According to news reporting from Inchon, South Korea, by NewsRx journalists, research stated, "In this study, we propose a novel micro-/nanofluidic device that can generate a chemical concentration gradient using a parallel nanochannel as gradient generator. This device is easy to fabricate, showing high reproducibility."

The news correspondents obtained a quote from the research from Inha University, "Its main feature is the multiple-nanochannel-based gradient generator, which permits the diffusion of small molecules and tunably generates concentration gradients. The nanopattern for the nanochannels can be rapidly and easily fabricated by wrinkling a diamond-like carbon thin film which is deposited on a polydimethylsiloxane substrate; the generation of the concentration gradient can be adjusted by controlling the dimensions of the nanochannels. The developed gradient generator is embedded into a microfluidic device to study chemotaxis in the nematode Caenorhabditis elegans, which has a highly developed chemosensory system and can detect a wide variety of chemical molecules."

According to the news reporters, the research concluded: "This device shows good performance for rapid analysis of C. elegans chemotaxis under sodium chloride stimuli."
