ENIGMA post doctoral fellow developed the application of ACEK-enhanced capacitive sensing technology as a rapid screening tool for the detection and quantification of microbial abundance in aquatic environments, such as groundwater wells at our Oak Ridge field site. As a proof of principle, she applied the tool to samples from ORNL and the Great Australian Bight.
New Science & Significance
- Results demonstrate that ACEK capacitance-based sensing can detect and determine microbial cell counts throughout cellular concentrations typically encountered in naturally occurring microbial communities (103-106 cells/mL).
- This work provides a foundation for understanding the limits of capacitance-based sensing in natural environmental samples and supports future efforts focusing on evaluating the robustness ACEK capacitance-based within aquatic environments.
