In this video we present the microfluidic probe1 (MFP). We explain in detail how to assemble the MFP, mount it atop an inverted microscope, and align it relative to the substrate surface, and finally show how to use it to process a substrate surface immersed in a buffer solution.
FAQs
Stability comes from maintaining a fixed mechanical relationship between the probe and its target while limiting vibration and unintended displacement. This steadiness helps preserve the probe’s angle and depth during recording, stimulation, microinjection, or imaging. As a result, measured signals or delivered interventions are more consistent, making differences between experimental preparations easier to interpret.
These components connect the probe to a stereotaxic frame or micromanipulator and provide different forms of positional control. Clamps grip the probe, adapters accommodate interfaces, and adjustable mounts help set its angle, depth, or movement. Choosing the appropriate combination allows researchers to match the holder to the instrument and the spatial demands of the experiment.
Angle, depth, movement, and resistance to vibration are central alignment factors. If the holder does not maintain these conditions, the probe may shift relative to the target, reducing targeting accuracy or signal consistency. Careful alignment therefore affects both experimental reliability and tissue protection, especially when the probe must remain precisely positioned throughout a measurement or intervention.
The suitable holder depends on the probe’s function and the positional control that function requires. Recording and imaging benefit from stable placement that supports consistent signals or observations, while stimulation and microinjection require controlled positioning relative to the target. In each case, the holder must support the needed angle, depth, and movement without damaging the probe or tissue.
A typical workflow is to secure the probe with a clamp or compatible adapter, attach the holder to the stereotaxic frame or micromanipulator, and align the assembly with the intended target. The researcher then controls the probe’s angle, depth, and movement while checking that the placement remains stable. This sequence supports reproducible positioning across preparations.
A specialized holder is particularly valuable when an experiment depends on accurate targeting, repeated positioning, or stable measurements from a delicate probe. It can support electrophysiological recording, neural stimulation, microinjection, or imaging when ordinary support would allow vibration or displacement. Selecting and aligning the holder carefully can improve reproducibility while reducing risks to both probe integrity and tissue.
