One of the advantages that micro-electrodes and microelectrode arrays offer is to allow the determination of trace chemicals with lowered limits of detection – this offers many advantages for the determination of for example explosives or airborne toxins for homeland security purposes. Micro-electrode arrays can in this context be coupled with air-borne cyclone systems such for continuous air monitoring.

Micro-electrode arrays are ideal for the determination of trace pollutants such as pesticides due to the lowered limits of detection they offer as detailed within the papers:

• Ultra-Sensitive determination of pesticides via cholinesterase-based sensors for environmental analysis.

• Construction of an enzyme containing microelectrode array and use for detection of low levels of pesticides.

In one example, Paraxon, an organophosphate pesticide was determined down to the level of 10^-17M using a bespoke flow injection analyser (FIA) as seen below.

As a generic enabling technology our microelectrode sensor manufacturing technique is applicable to sensor technologies for many diverse applications including:

• •Potable Water and Pool / Spa Sector
• •Environmental Monitoring
• •Sensors for Healthcare and Biomedical Applications
• •Homeland Security and Environmental Air Quality Applications
