Abstract
The results of study on the chemical deposition of polymeric coatings of a nanoscale thickness on porous and flat inorganic matrices and encapsulation of nano-and microparticles in polymer shells are discussed. Procedures for the deposition of homogeneous defect-free coatings are detailed by using polytetrafluoroethylene, polyaniline, and their derivatives as examples. The matrices modified with nanosized polytetrafluoroethylene and polyaniline layers are promising biomaterials for one-step isolation of nucleic acids from complex biological mixtures (cell and tissue lysates, whole blood, plant feedstock), as well as for high-performance chromatography of proteins and other biopolymers. Approaches to the fabrication of polymer shells on luminescent nanocrystals of (CdSe)ZnS via the inclusion of the nanocrystals in micrometer-sized particles based on acrolein-styrene copolymers and the formation of polymer shells directly on nanoparticles are discussed. It was shown that polymer-functionalized luminescent nanocrystals hold promise as bioanalytical reagents.
