Driven by cutting-edge technologies
Microfluidic Diffusional Sizing
Rapid and easy determination of hydrodynamic sizes and interactions of biomolecules in solution
Get to know Microfluidic Diffusional Sizing (MDS), the technology that drives our products. MDS gives one simple and direct measurement – protein molecular size. When binding occurs, changes in protein size are monitored and used to determine binding affinity and calibration-free concentration or binding stoichiometry.

Picodroplet Microfluidic Technology
The core of our Cyto-Mine® platforms
Each picodroplet is used to encapsulate a cell. The chemistry of the emulsions is carefully designed to give long-term stable, biocompatible droplets with minimal leakage of molecules from the droplet, right down to small molecules such as metabolites. This provides an ultra-miniaturized test tube, containing media, reagents, and cells, that allows large-scale experiments at the single cell level.
