Crystal Diagnostics

Crystal Diagnostics’ 7,000 square foot state-of the art production facility located at the Centennial Research Park at Kent State University. The plant produces the BioCassettes and Antibody Kits used to detect targeted pathogens.

Crystal Diagnostics was born out of a research partnership with Kent State University and Northeast Ohio Medical University. The company’s mission is to bring new technology solutions to pathogen detection using liquid crystal technology.  After 14 years of R&D and 19 patents and counting, Crystal Diagnostics has developed a new platform in food safety testing that is superior to PCR on virtually every measure:


Today, Crystal Diagnostics offers the first-ever Liquid Crystal Biosensor with commercial application for testing beef, chicken, produce and environmental surfaces. We have offerings for the detection of Big 6 STECs, Salmonella, Listeria and E. coli O157; available immediately and AOAC accredited. Crystal Diagnostics’ Xpress System offers a new option for food companies looking to save time and costs while improving reliability of their overall food and environmental testing protocols.


A 14 year R&D partnership between Crystal Diagnostics and The Liquid Crystal Institute at Kent State University has resulted in a breakthrough in food safety testing. Crystal Diagnostics is excited to introduce CDx, a new platform for pathogen detection. The first and only based on Liquid Crystal Biosensors.

The difference between CDx and PCR is night and day. Literally. CDx can provide results in under 10 hours vs. up to 24 hours or longer for typical PCR results. That’s because CDx is based on a mechanical reaction between targeted pathogens and antibodies, while PCR is based on a slower, biological reaction of DNA replication. The differences are dramatic. From speed to convenience and accuracy CDx offers multiple benefits over PCR. Read more
