Value Proposition
· Increased sensitivity: A better way to detect ultra-low levels of particulates
· Specificity: An ability to discriminate the chemical functional groups of various particulates
Unmet Need
· Electrochemical particulate sensors, while promising, have been largely contained to research settings. While their exists a need for better particulate sensing technology, slow processing and ineffiencies in detection have limited the advancement of these technologies (Barhoum, 2023). Thus, there exists a strong need for developing a more precise, efficient method for sensing airborne particulate matter with electrochemical sensors.
Technology Description
· Researchers at Johns Hopkins have developed a method to advance electrochemical particulate sensors by using organic field effect transistors. This technology eliminates the need for electrochemical cells that typically are challenging to utilize in low cost and timely methods.
Stage of Development
· Benchtop proof of concept has been demonstrated.
· Current efforts focus on streamlining the production process and further enhancements of response selectivity.
Data Availability
· Data available upon request.
