Domain Where Physics, Chemistry, Biology, and Technology Meet (see above) p. 11. The paper, Use of quantitative structure-property relationships in predicting the Krafft point of anionic surfactants by M. Jalali-Heravi and E. Konouz, Internet Electronic Journal of Molecular Design, 2002, 1, 410, has a nice introduction and useful references. It can be downloaded at http //www.biochempress.com/av01 0410.html.

The interferons (IFNs) are a family of proteins produced by nucleated cells and by recombinant DNA technology, with antiviral, antiproliferative, and immunoregulatory activities. They are classified as a, p, or Y interferons based on antigenic, biologic, and pharmacologic properties. Many subtypes of IFN a are known. IFN a-2a and IFN o -2b, approved for anticancer indications, are very similar single-species recombinant products. 

Microemulsions and most surfactants in dilute solutions and dispersions self-assemble into a variety of microstructures spherical or wormlike micelles, swollen micelles, vesicles, and liposomes. Such systems are of biological and technological importance, e.g., in detergency, drug delivery, catalysis, enhanced oil recovery, flammability control, and nanoscale particle production. The macroscopic properties—rheology, surface tension, and conductivity—of these systems depend on their microstructure. As these microstructures are small (1-1000 nm) and sometimes several microstructures can coexist in the same solution, it is difficult to determine their structure. Conventional techniques like radiation scattering, although useful, provide only indirect evidence of microstructures, and the structures deduced are model-dependent.
