NO Microsensor

Measure minute concentrations of nitric oxide

Nitric oxide plays an important role in many biological processes. However, natural concentrations are often in the nanomolar range. The Unisense NO microsensor is characterized by a very high sensitivity, which enables you to measure minute concentrations of NO. Combined with a fast response time the Unisense NO microsensor is an excellent research tool for a broad range of tasks.

The sensor can be used equally well for NO measurements in tissue, air, or liquid, and is applied in a broad variety of research fields where non-destructive, fast, and accurate measurements are required.

The NO microsensors are Clark-type sensors measuring the external NO partial pressure. The working principle of the sensor is based on diffusion of NO through a silicone membrane to an NO oxidizing anode, which is polarized against an internal counter cathode. The resulting sensor signal is in the pA range and is measured by a high quality picoammeter, such as the UniAmp Multi Channel.

Compared to other standard NO sensors, the Unisense NO microsensor has an extremely low consumption of max. 935 pmol/hour corresponding to 0.1%/hour in a 1 mL 0.1uM NO sample.
