FIDA: Flow Induced Dispersion Analysis
I'm Interested

FIDA technology embodies first-principles thinking.

It uses first principles of physics and fluid mechanics to analyze the movement of particles in a fluid.
Thanks to its simplicityit can deliver a wealth of datawith just one assay.

1. Laminar Flow

Laminar flow is a smoothnon-turbulent flow of a fluid pushed through a capillary. In a laminar flow regimethe fluid moves in parallel streams.

2. Taylor Dispersion

Taylor dispersion describes the behaviour of small particles in the flow. As the flow is laminarthe particles will not mix evenlybut instead experience a fluctuating motion. Such a motion results in a dispersion of the particles over time and spaceas they diffuse and move along the flow.

FIDA technology takes advantage of these two principles

by measuring fluorescence of particles in the laminar flow and analysing their dispersion over timewhich allows for calculation of the hydrodynamic radius of a particle of interest.

Additionallyhydrodynamic radius measurement opens door to another crucial biophysical property: the binding between two or more biomolecules

As biomolecules come together and bind in solutiontheir diffusivity (D) decreases; that isthe bound molecules will diffuse slower through the capillary and generate a more extended dispersion profile and diffusion coefficient (D). Using the Stokes-Einstein equationFIDA software reveals the increase in size (Rh) of the molecules as they bind together. Titrating your molecule of interest with its binding partners in a simple FIDA experiment uncovers a wide range of binding parameterssuch as affinity (Kd)derived directly from the hydrodynamic radius and the Stokes-Einstein equation.

See it step by step:

If anything remains unclearfeel free to reach out
Ask a question to our scientist

Step 01

The sample of interest is passed through a thin capillary. Due to the difference in velocity between the walls and center of the capillarythe sample shapes into a parabolic profile.

Step 02

Molecules diffuse radiallyaway from the flow axis. The fluorescence emitted by the molecules is acquired as a Gaussian signal by a high sensitivity detection system and is plotted against time.

Step 03

The size of the molecules in the sample determines their radial diffusivitywhich in turn defines the extent of sample’s dispersion.

Small molecules diffuse faster and create a more compact dispersion profile. Large molecules diffuse slower, which results in a more extended dispersion profile.

Step 04

The math behind the software calculations is based on Taylor dispersion phenomena and the Stokes-Einstein equation, which provide a firm base for further calculations.

Are you wondering if FIDA is the right solution for you?

Watch the video to see how it works

How do FIDA users benefit from the first principles?

Accuracy

Since FIDA is not dependent on a priori assumption or on empirical calibrationit ensures accuracy and provides flexibility in analysing diverse samples.

Data Transparency

On top of thathaving direct measurements translates into high data transparencynecessary for quality control or even machine learning.

Certainty

Finallythe chance that your measurements do not reflect realityare impreciseor are a false positive/negative is much lower in first principle technologies. To be frankwe think that first principle technologies are the future.
