Emulsions for Single Immunocomplex Micromechanics

To measure the force-extension law of a small biomolecule, these authors employed a two-step strategy. First, the background repulsive force-distance profile, in the absence of biomolecules, Fbg(h), is measured, h being the interparticle spacing. Then, once the biocomplexes have been properly attached within each interval between colloids, the same measurement is repeated, allowing determination of the force-distance profile of this irreversible assembly The force / (/t) 

These two examples show how emulsion-based magnetic colloids can become the essential elements for two apparently very different issues. In fact, this section introduces the basics of using superparamagnetic emulsion-based colloids, and their spontaneous self-assembling ability under a field, as new biosensors. The
