FORCE SPECTROSCOPY

FOR CELL MECHANOBIOLOGY & BIOPHYSICS.

Both in biophysics and mechanobiology, the physical study of single cells allows insights into biological phenomenon such as differentiation, growth and proliferation. In cancer research, stem cells, and organoids, the cell mechanical properties and interactions with its environment are key to obtain a deeper understanding. Further, for implant materials there is a clinical need to understand and control how various cells adhere to it.

With each cell being different from its neighbor – also known as cell heterogeneity - one goal is to understand these effects on a single cell level. Single cell force spectroscopy has been established as an insightful method to address such questions using atomic force microscopy (AFM). 

The process of gluing a cell to an AFM cantilever is however tedious and time-consuming, limiting the throughput to few cells per day. Yet due to cell-cell heterogeneity many cells are typically needed to meaningfully assess any experimental condition.

Here, the FluidFM BOT BIO Series offers a dramatic improvement, by reversibly immobilizing a cell to a FluidFM probe by suction, and subsequent release with pressure. This allows the increase of the throughput by a factor of 10 to 100.

LARGEST FORCE RANGE. HIGHEST FLEXIBILITY.

Reduced preparation time in combination with reusable measurement probes makes FluidFM the perfect tool for all your single cell mechanical studies.

Thanks to the unique properties of FluidFM technology, you can gather solid cell mechanical data in a much shorter time. Gain access to unparalleled measurement ranges, increasing your experimental flexibility.

Measure suspended or fully adherent cell

FluidFM micropipettes allow to either attract a suspended cell from solution or to directly pick it up from fully adherent culture. FluidFM can thus overcome cell adhesion forces of more than 1000 nN.


Pick. Measure. Clean. Repeat.

With many mammalian cells having a tendency to adhere quickly to any substrate – also the FluidFM probe – a common approach is to clean the probe after each cell. With the automated built-in probe-washing feature, the procedure takes less than two minutes before picking up the next cell for measurements. For non-adherent cells, this cleaning procedure can be skipped, and the throughput is even higher. 


Direct measurement in physiological conditions.

Understanding cell-adhesion to surfaces means understanding how a cell senses the environment and reacts to it. FluidFM allows to measure adhesion forces directly in the cells environment, preserving cellular context.

Optimizing drugs

Millions of people suffer from Leukemia around the world. While treatment drugs exist, cancer regularly develops a resistance against them. Researchers from both the University Hospital Würzburg and the University Würzburg found a new potential approach to overcome resistance to the recently approved Midostaurin drug and even increase the drug activity, also with help of FluidFM cell measurements.

Optimizing stents

Stents help millions of people every year to overcome arterial blockages, saving many lives in the process. Once implanted, the stent should integrate well and prevent formation of blood clots. In this publication research groups from ETH Zurich investigate stent design optimization by measuring cell adhesion to its surface with FluidFM.

Calibrating high-throughput devices

Single cell force spectroscopy offers fundamental insights into many fields yet suffers from low throughput. MTA Budapest tremendously speeds up the acquisition of single cell adhesion data by using FluidFM adhesion measurements to calibrate an optical sensor array. Thus, they are able mechanically monitor more than 1000 adherent cells in parallel.
