We develop novel electrodes which provide users with a powerful platform for the development of electrochemical sensors. Applications of our sensors include, but are not limited to, the fields of biochemistry, clinical biochemistry, and the life sciences. Camstech electrodes offer a number of advantages over conventional screen-printed electrodes: they are suitable for in-vivo and/or in-vitro analysis, offer high spatial resolution and work with microvolume samples. Our electrodes are particularly suitable for continuous monitoring because they demonstrate improved stability and resistance to biofouling compared with conventional electrodes.
The Camstech DO sensor is available in two different formats: needle and planar. Both sensor types are compatible with standard potentiostats. The needle sensor was originally developed for in vivo applications however it could be adapted to other user specific needs. The planar sensor is compatible with different thin-layer flow cells.
Electrochemical sensors operate by reacting with the analyte of interest and producing an electrical signal proportional to the analyte concentration. A typical electrochemical sensor consists of a sensing electrode (or working electrode), and a counter electrode separated by a thin layer of electrolyte.
There are battery-powered and handheld potentiostat/galvanostat as well as more sophisticated and expensive benchtop instruments, which allow the application of most of the relevant voltammetric and amperometric techniques, as well as impedance analysis (EIS). Camstech electrodes are compatible with most potentiostats/galvanostats available on the market.
Electrochemical sensors are used in a large number of different applications with Dissolved Oxygen sensing being one of the simplest and most popular. Camstech also offers two standard enzymatic sensors for glucose and lactate.
Camstech sensors work well for continuous monitoring applications. They were designed to reduce or completely eliminate electrode drift and to resist biofouling. Our sensors could be integrated into various flow cells and microfluidic systems.
