The simultaneous concentration and recovery of microbes in drinking water is important for responding to potential water-related events such as pathogen contamination or bioterrorism and could be a cost-effective technique for routine monitoring of drinking water quality. Scientists at the CDC have combined two techniques, ultrafiltration (UF) and insulator-based dielectrophoresis (iDEP) in series, to achieve significant concentration of microbes and pathogens for analysis.

The CDC Technology Transfer Office (TTO) is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize a system to monitor water supplies for a variety of pathogens. For collaboration opportunities, please contact CDC TTO at tto@cdc.gov or 1-404-639-1330.
- A rapid method for detecting the presence of a variety of microbes such as Cryptosporidium parvum oocysts and Enterococcus faecalis
- Uses a combination of ultrafiltration and dielectrophoretic separation techniques versus available single method technology
- Ability to separate live from non-viable microbes, thereby decreasing the chances of generating false-positive PCR results due to the presence of naked nucleic acid or non-viable microbes
- Accurately assess low levels of pathogens in finished drinking water samples, whether due to natural or intentional contamination
Monitoring
(Public Health/Counterfeit Detection/Biological)
- Monitoring of municipal, commercial, public, and individual water supplies for drinking water quality
- Monitoring source water, industrial effluent, hospital discharge, and military water infrastructures for pathogens
- Assessing water in agricultural settings
- Monitoring water quality in pools and other recreational settings
