FluidFM® ADD‑ON for Bruker & JPK AFMs
To extend the capability of your Bruker AFM with FluidFM ADD-ON, contact our partner:
Extend the application scope of your Bruker or JPK atomic force microscope with our FluidFM ADD-ON. The FluidFM ADD-ON is compatible with the Bruker BioScope Resolve AFM and all JPK NanoWizard®, ForceRobot® and CellHesion® AFMs.
Safe & reliable
The custom FluidFM probe holder for your AFM assures safe, tight and reliable mounting of FluidFM probes without the need of any tweezers.

Easy & fast probe mounting
The mounting of a FluidFM probe onto your AFM is fast and simple and does not require any tooling. The video shows the mounting onto a JPK NanoWizard AFM.
Tailored to each system
Our FluidFM probe adapters are tailored to the geometrical and physical requirements of the specific JPK and Bruker AFMs.
Use Cases with a FluidFM ADD-ON and Bruker & JPK AFMs
Mechanobiology
Original video length ~10 min. Video courtesy of Bruker.
Quantification of cell - surface interaction
The interaction of a H431 cell is being quantified against the surface on a 8x8 array. The experiment was conducted with a Bruker BioScope Resolve and a FluidFM micropipette.
Pick up of a bead for force mapping on living cells
Original video length ~9 min. Video courtesy of Bruker.
A colloid is picked up by a FluidFM probe and used to measure a force map on a living cell. The FluidFM microfluidic control is fully integrated into the AFM software. The bead is held with -400 mbar while the measurement takes place. The video shows a full force map cycle.

Creating droplet arrays from fL to nL
In this video the letters JPK are spotted onto a glass dish in air. These femtoliter sized water droplets quickly evaporate under ambient conditions. For longer lasting droplets a bit of glycerol can be added to the ink. However, often it is desired that only the proteins or nanoparticle payload stays on the sample, while the carrier solution evaporates.
Reproducibility of FluidFM printed spots
3x4 spots of 30 nm gold nanoparticles are deposited with a FluidFM probe
- They are later scanned with the same probe
- The reproducibility of all 12 spots is very high
- The slope channel is extremely useful to calculate the spot area and volume
- The 30 nm Au nano particles are individual or aggregated, and typically slightly to the edge of the spot

Print & scan with the same probe
AFM scans are also possible with the FluidFM nanopipette used for printing. Yet doubled features occur due to the tip geometry, which features corners around the opening. 2 of which at the contact level. These doubled feature effect can be avoided by tilting the AFM.
