Hydrogel films are used in many applications. One type of interesting application are where control of the hydrogel film thickness is important, such as fluorescence based hydrogel sensor. In other sensor, such as Aptamer based DNA hydrogel film sensor, the thickness measurement is used for detection of the target protein.
Hydrogels have high concentration of water but they also also have particles and gel formations that can cause light scattering. For good optical measurement, it is important to optimize the spot size and has a perfect match for this measurement.
Hydrogel film thickness during process development can be very non-uniform. MProbe system allows to measure thickness distribution quickly to help process optimization.The measurements analysis is using proprietary – this reduces the need for calibration and make it well suited for inline measurements in production. MProbe system can provide 24/7 with data output over TCP or in analog form(for PLC integration)
