This Fidabio brochure introduces Fida Evolve, a multi-readout biophysical characterisation platform based on Flow Induced Dispersion Analysis (FIDA). A single in-solution assay captures three simultaneous measurements — absolute molecular size (hydrodynamic radius), Lambda Dynamics (ratiometric fluorescence) and Binding-Related Intensity Change (BRIC) — yielding more than ten label-free readouts including binding affinity (picomolar to millimolar), binding kinetics, aggregation, polydispersity, viscosity, quantification, sample stickiness and labelling quality, all in native conditions from nanolitre–microlitre samples. It also adds a Rapid-KD method for one-minute affinity screening and a PDB Correlator that checks measured size against structural models such as AlphaFold. It is an example of the FIDA platform for label-free, in-solution biophysical characterisation.
