  • Method for producing polymer coating on particle surfaces
    Patent number: 8691347
    Abstract: The invention concerns the methods for producing polymeric coatings on particle surfaces and can be used in pharmacology, medicine, veterinary and cosmetology to create the systems of vector delivery of drugs and biologically active agents as well as in other fields applying the particles with thin-layer polymer coatings. The method enables to obtain biocompatible, particularly polyamide and polyimide coatings on inorganic particles including magnetic inorganic nanoparticles. The method for producing polymeric coatings on particles surface comprises (a) forming a reaction system containing the particles mixed with monomers, and (b) the subsequent carrying out of polymerization reaction to form the polymeric coating on the particles; wherein the said polymerization reaction is accomplished by irradiating the reaction system with electromagnetic radiation, particularly, with microwaves capable of being absorbed partially or totally by the said particles.

  • Raman-active taggants and thier recognition
    Publication number: 20040058058
    Abstract: An organic or organoelement, linear or branched, monomeric or polymeric composition of matter having a Raman-active component in the form of particles. The particles having a maximum dimension of 50 &mgr;m. The Raman-active compound is applied to a substrate. When the Raman-active compound is exposed to a laser light wavelength which is batochromically well beyond a spectral region of maximum absorbance of said Raman-active compound, Raman scattering can be detected.
