02 / Semiconductor nano-/ microparticles
Nanoparticles e.g. TiO2, ZnO as a colloidal suspension or as
a powder with photocatalytic and antibacterial properties. Particle shapes: spherical, decaedral. Particle size range:
10-200 nm, depending on shape. Possibility of surface modification with noble metal nanoparticles. Potential applications include self-cleaning surfaces, odor neutralization, air and water purification, solar cells.
03 / Semiconductor materials in the form of thin layers
Layers formed from TiO2 nanoparticles, TiO2 nanotubes or carbon nanotubes for photocatalytic applications,self-cleaning surfaces
04 / Noble metal nanoparticles
Ag, Au, Cu nanoparticles with antibacterial and antifungal properties. Good optical, electrical and thermal properties, making them an attractive material for many industrial sectors: optoelectronics, biotechnology or textile industry.
Suspension in water or in other solvents such as ethanol, isopropanol. Stability in both diluted and concentrated systems for 6 months.
Design and construction of the reactor for obtaining nanoparticles was financed as part of the "Incubator of Innovation +" project implemented by the University of Gdańsk as part of the Intelligent Development Operational Program 2014-2020 No. MNISW/2017/DIR/68/II+, 29/03/2017.
05 / Quantum dots (QDs)
Semiconductor nanocrystals with particle size range: 2-10 nm. QDs are characterized by a wide range of absorption and narrow, symmetrical emission of fluorescence, high photo-stability, and very long radiation emission time. It is possible to produce quantum dots with selected physicochemical parameters due to their unique optical properties dependent on the size and shape of the particles.
The ability to functionalization quantum dotsby appropriate ligands allows them to attach appropriate biologically active substances so that quantum dots are used as drug carriers and can be used in diagnostics and treatment.In addition, quantum dots are widely used in next-generation photovoltaic cells, optics, optoelectronics, and environmental protection.
Types of quantum dots: CdTe, CdS, CdSe, ZnO, Bi2S3, carbon, graphene.
06 / Nanotubes
Thin TiO2 nanotube layers, obtained by anodizing titanium foil (or titanium alloy), sol-gel and hydrothermal methods. The basic advantage of the TiO2-oriented thin films in comparison to powdered materials is a much larger surface area and therefore higher activity. TiO2-oriented nanotubes have a number of uses, mainly in catalytic and photocatalytic processes (in a modern photocatalytic devices), in solar cells, electrochromic systems, biomedicine, for example as drug delivery capsules, also as implants and biosensors.
We also have experience in the preparation of other types of nanoparticles: SrTiO3, KTaO3, WO3, KNbO3, luminescent materials, rare earth orthovanads.
