Polymeric, Inorganic, and Colloidal Nanoparticles

Description

Surface-active oligoperoxides and oligoperoxide metal complexes have been developed and are being utilized for the production of the following functional nanoparticles:

  • Polymeric nanoparticles including fluorocontaining ones (40-100 nm), i.e. polystyrene and polyacrylate, with tailored particle size distribution, functionality and reactivity;
  • Reactive functional nanoparticles with magnetic, conductive, resistive and dielectrical properties: ferric oxide based nanoparticles (8-12 nm), Ag (10-20 nm), Cu (500 nm), Ni (1-2 micrometres);
  • Biocompatible colloidal particles capable of binding proteins and interaction with cell membrane, which are based on polymeric, ferric oxide, and Ni nanoparticles;
  • Water-soluble oligomeric surfactants capable of improving the solubility of drugs and water based preparations;
  • Luminescent oligomeric and colloidal cell markers.

Innovative Aspect and Main Advantages

Available production processes include, but are not limited to, radical polymerization and homogenous nucleation. Developed oligoperoxides and oligoperoxide metal complexes are of linear, block- and highly branched structures (including fluorocontaining chains or branches).

Areas of Application

Possible applications are in microelectronics, biotechnology, surface modification in particular (water repellents, antimicrobial coatings, fillers, fibers and fabrics).
