Synthos Generation

For many years, Colloids Research Group (Institute of Catalysis and Surface Chemistry, PAS) brings together specialists in the field of synthesis of various functional colloidal particles and surfaces. Preparation of colloidal particles with desired physicochemical properties has an essential significance for their efficient application. In our lab, size, morphology and surface properties of nano- and microparticles are modeled during their synthesis. Further functionalization of nano- and microparticle surfaces enables their selective binding to target molecules such as drugs and enzymes. Due to many year experience in the synthesis of monodisperse gold and silver nanoparticles, our offer is addressed mainly to the medical and biotechnological companies. Offered silver nanoparticles exhibit antitumor and antibacterial properties, which has been documented by numerous scientific publications. On the other hand, functionalized noble metal particles exhibiting pronounced plasmonic properties are extensively used in various analytical methods such as surface enhanced Raman spectroscopy (SERS). Additionally, the development of efficient methods of immobilization of nanoparticles on various substrates (supports) is important for catalysis. The another example of functional system synthesized by our specialists are polymer microparticle suspensions (latexes). In contradiction to the vast majority of commercially offered polymer particles, our systems are prepared without the addition of stabilizers and surfactants. For this reason, our polymer microparticles are applied as effective protein carriers (mainly immunoglobulins), cores for the production of microcapsular carries and model systems for the studies devoted to phagocytosis. We supply latexes to commerical companies producing immunological tests such as the assay for rapid detection and identification of Shigella sonnei antigens, the test of detection of antigens of enteropathogenic rods of Escherichia coli (EPEC), Staphylococcus aureus and Salmonella. Besides ready-made particle solutions we are offering services in the field of nano- and microparticles characterization including determination of particles morphology, size distribution, density, porosity, hydrodynamic diameter and electrokinetic properties. Our group is also specialized in the characterization of macroscopic surfaces. In this case, we are able to determine morphology, roughness, surface charge density, reflectance and other properties of surfaces which are essential for their applications. The analyzes are performed using high-class equipment (AFM microscopes, Malvern Zetasizers, Shimadzu spectrophotometers), and our priority is their repeatability and reliability.

Type of offer:

Our offer is mainly addressed to representatives of the medical, biotechnological, pharmaceutical, cosmetic and household chemicals companies. We propose various forms of collaboration with both companies and research departments. For testing purposes, we can provide a free samples of our products. Additionally, we look for the companies interested in the purchasing our technologies of production in the form of license or know how agreements. We guarantee high quality of our products which is confirmed by thorough physicochemical analysis. Additionally, we are open to new challenges in the preparation of colloidal systems characterized by the properties desired by clients. We provide reliability and competitiveness.
