Surface active and rheological properties of lipids of different origins at the polymer/water interface

In recent years, intensive investigations on the synthesis of polymer suspensions containing microspheres of various diameters with a narrow size distribution have been carried out for their use as bioligand carriers in immunoassay. In this context, lipids are rather promising, because they exhibit surface-active properties and are used as SAS during the synthesis of polymer suspensions; at the same time, lipids containing phosphatidylcholine have a property to interact specifically with a C-reactive peptide [1–3]. These properties of the lipids are reasonable to use for the creation of test systems for the definition of a C-reactive peptide by the latex agglutination reaction method (LAR), in which the polymeric microspheres containing phosphatidylcholine on their surface are used as bioligand carriers.
