Fida Biosystems

Fida Biosystems has developed a unique biophysical analysis platform, FIDA, which simplifies and accelerates the study of molecular interactions directly in solution. The technology delivers over ten critical parameters—such as binding kinetics, affinity, and hydrodynamic radius—from a single, automated assay using minimal sample volume, addressing key bottlenecks in biopharmaceutical R&D. Its instruments are praised by industry and academic users for ease of use, buffer flexibility, and the ability to analyze difficult targets without surface immobilization. Positioned at the intersection of proteomics and diagnostics tools, Fida is enabling more efficient decision-making in early-stage research and development.

Flow Induced Dispersion Analysis (FIDA): An in-solution, microfluidic-based technology that measures changes in hydrodynamic radius and fluorescence to characterize molecular interactions (affinity, kinetics, size) using nanoliter sample volumes in any buffer matrix, without requiring surface immobilization.

Fida competes in the biophysical characterization market against established techniques like Surface Plasmon Resonance (SPR), Isothermal Titration Calorimetry (ITC), and Dynamic Light Scattering (DLS). Its key competitive advantages are minimal sample consumption, buffer flexibility, analysis of unpurified samples, and the ability to study targets that suffer from non-specific binding in surface-based assays. It positions itself as a complementary, high-information-content tool rather than a direct one-to-one replacement.
