UNCD Sensor Substrates
Case Study 1
Application: Waterborne pathogen detection
Problem: The Defense Threat Reduction Agency (DTRA) needed a bio-activated substrate that could selectively sense pathogens in water, but needed the antibody functionalized substrate to stay biologically active and stable for longer than the industry standard, silica.
Solution: UNCD Aqua 25 functionalized with anti-E.coli O157:H7 proved to be stable for up to two weeks at body temperature, and at least six months under refrigeration (4 °C).
Finding: Researcher can use UNCD Sensor substrates as a better alternative to glass slides when bio-stability over the long term and reusability of the functionalized surface (up to 30 hybridization/denaturation cycles) is critical.
Case Study 2
Application: Pharmaceutical waste detection
Problem: The Environmental Protection Agency (EPA) needed a sensitive electrode array for detecting a suite of Contaminants of Emerging Concerns (CECs) in-situ in waste water treatment facility.
Solution: UNCD Aqua 25 sensor arrays with electroactive area as small as 0.008 mm2 are ideally suited for ultrasensitive electrochemical detection of redox active pollutants. The signal-to-noise ratios are at least 2 orders of magnitude higher than the conventional macroelectrodes used for electrochemical based detection.
Finding: Researcher can use UNCD Sensor array substrates as a better alternative to conventional metal and carbon electrodes when sensitivity and multiplexing (i.e. measuring a suite of analytes) is critical.
