NO Microsensor

NO microsensor with tip diameter of 100 µm.
The NO microsensor can be mounted in a sensor guide to fit with the MicroRespiration system.
The NO microsensor can be mounted with a steel needle to make it stronger on the longitudinal axis.
The NO microsensor signal must be amplified by a Unisense amplifier e.g. the laboratory Microsensor Multimeter.
The graph shows an NO sensor response to sequential addition of 12 nM NO. Data points were taken every second. Each of the shown p...
The NO microsensor has been widely used in brain research applications.

Measure minute concentrations of NO

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 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 microsensor is designed for research applications within:

  • Environmental sciences
  • Biomedical sciences
  • Biotechnology
  • Wastewater

Microsensor technology:

The NO micro- and minisensors 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 e.g. the Unisense Microsensor Multimeter.
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.
