How can I customize the probe aperture? Prototyping probes

FluidFM Probes


For some applications, a non-standard aperture is required for FluidFM probes. Therefore, we offer FluidFM rapid prototyping probes, where the aperture of the probe can be shaped with a focused ion beam (FIB) as desired. 

Usually, we recommend the following procedure:

  1. Deposit a carbon coating on the probe to avoid charge effects. 

  2. Mill the aperture into the FluidFM rapid prototyping probe using FIB.

  3. Inspect the probe using a scanning electron microscope. 

  4. Remove the carbon coating with a 2 minute O2-plasma treatment. 

  5. The custom FluidFM probe is now ready to use. 

On request, we also offer to perform these rapid prototyping operations. The price will depend on the complexity of your design and the number of probes. Do not hesitate to contact us for more information on [email protected].
