- Flexible sensor, nearly unbreakable
- In vivo nitric oxide measurement
ISO-NOPF electrodes are available in 100 µm, 200 µm and 500 µm diameters. Utilizing the latest advances in nano-technology and material science, scientists at WPI’s Sensor Laboratory have created these completely flexible and virtually unbreakable NO sensors. The new sensors are based on a composite graphite NO-sensing element combined with a reference electrode. The surface of the sensor is then coated with a unique multi-layered NO-selective membrane.
Unique, flexible NO sensor
Designed for arteries, microvessels, in vivo applications, and similar applications. The graph (right) shows the response of the ISO-NOPF to NO.
These sensors are based on a composite graphite NO-sensing element combined with a reference electrode. The surface of the sensor is then coated with a unique multi-layered NO-selective membrane.
Selectivity of WPI's NO sensors
The ideal NO sensor should be insensitive to other reactive species likely to be present within the measurement environment. Conventional Nafion coated carbon fiber NO sensor exhibits a large response to such species. WPI's unique NO sensor technology utilizes an novel surface membrane which amplifies the response to NO whilst eliminating responses to a vast range of reactive species, including nitrite, ascorbic acid, hydrogen peroxide, catecolamines, and much more.
NOTE: ISO-NOPF200 is a 5mm long sensor, custom lengths available (1, 2, 3, 4 mm). When ordering custom lengths, use the part number ISO-NOPF200-CXX and replace the XX with the desired length. For example, if you want a 1 mm flexible sensor tip, the part number should be ISO-NOPF200-C01. This sensor can be ordered in the following custom lengths: 1 mm, 2 mm, 3 mm or 4 mm. Make your selection from the dropdown list before you place your order.
The ISO-NOPF500 is a nitric oxide sensor designed like the dry, carbon fiber ISO-NOPF sensors, however, it works like a traditional ISO-NOP 2mm sensor. The sensor can be ordered in a variety of lengths from 5-10mm. It incorporates WPI's propiretary combination electrode technology in which the nitric oxide sensing element and separate reference electrode are encased within a single sheilded sensor design.
The ISO-NOP was the original nitric oxide sensor, ideal for cell cultures, cell suspensions and many other applications. The new ISO-NOPF500 can be used in the same way, but offers several advantages:
- Requires no sleeves or filling solutions
- Flexible and durable, like other ISO-NOPF sensors
- High sensitivity for a rapid response time–ten times more sensitive than the ISO-NOP
- Can be used in acidic conditions
- Longer sensor tip than the ISO-NOP
- Bigger linear range than the ISO-NOP (range is based on the length of the sensor tip)
- Calibration with either the SNAP or Nitrite method
NOTE: When ordering custom lengths, use the part number ISO-NOPF500-CXX and replace the XX with the desired length. For example, if you want a 10mm flexible sensor tip, the part number should be ISO-NOPF500-C10. This sensor can be ordered in the following custom lengths: 5mm, 6mm, 7mm, 8mm, 9mm or 10mm.
The ISO-NOPF200-L10 is a unique L-shaped nitric oxide sensor designed specifically for use in tissue bath studies and similar applications. The shape of the sensor has been engineered to facilitate placement of the electrode within the lumen of the tissue vessel under study. The ISO-NOPF200-L10 has a flexible tip (200 µm diameter).
