Resumen:
An established Slovak research institute has developed polymer nanocomposite with antibacterial properties. The novel hybrid nanomaterial is composed of hydrophobic carbon quantum dots (hCQD) mixed with a polymer of choice (e.g polyamide, acrylics, butadiene, dialkylphtalate, dimethylsiloxanes, isoprene, etc.) in processes allowing manufacturing of different forms - coating, flexible film, foil, fiber and sheet. The research institute is looking for licensees or investors.

Summary:
An established Slovak research institute has developed polymer nanocomposite with antibacterial properties.The novel hybrid nanomaterial is composed of hydrophobic carbon quantum dots (hCQD) mixed with a polymer of choice (e.g polyamide, acrylics, butadiene, dialkylphtalate, dimethylsiloxanes, isoprene, etc.) in processes allowing manufacturing of different forms - coating, flexible film, foil, fiber and sheet.
The research institute is looking for licensees or investor.
Description:
Material is composed of cheap nanoparticles hCQD (carrier of antibacterial properties) and a polymer of choice and can be used in areas where antibacterial activity is desired, e.g in medical applications, clean pharmaceutical industry, food industry or in households in different forms - coating, films, sheets, foil, fibers. Novel nanocomposite materials and their manufacturing process are protected by a patent (so far a patent publication with very positive international search) and the research institution is the sole owner of the IPRs.
Polymers used for most of biomedical, food and pharmaceutical applications are not soluble in water. They are commonly soluble only in limited class of organic solvents such as chloroform or toluene. In order to overcome that problem new method was developed for the production of hydrophobic CQD (hCQD) soluble in chloroform or toluene. Size of hCQDs is between 5 and 15 nm. hCQDs are photoluminescent material i.e. when irradiated with certain excitation source they re-emit light usually in visible region of spectrum. This feature enables easy identification of
their composite (film) or in the interior of the composite.
It was demonstrated that hCQD produce singlet oxygen molecule by Electron paramagnetic resonance (EPR) spectroscopy. hCQD have shown steady production of singlet oxygen under blue lamp irradiation. After 7 minutes, spin trap was exhausted and EPR show decrease of singlet oxygen production. After addition of new amount of fresh spin trap, EPR shows identical production of singlet oxygen.
Nanocomposite can be produced by following methods: layer by layer (LbL) method, solution mixing methods and by electrospinning. hCQD are not soluble in water and therefore cannot interact or be degraded in body fluids comparing to commonly available antibacterial silver or titanium compounds.

The research institute is looking for partners to cooperate with via license agreement (the Slovak research institute is looking for licensees) or via financial agreement (an investor is sought). More details in the Partner Sought.
Advantages and Innovations:
· Low cost- hCQDs are cheaper than silver or titanium nanoparticles
· Ease of production
· Stability over time- no oxidation or reaction with air gases (in contrast, silver nanoparticles are prone to oxidation and loosing antibacterial effect after certain time)
· Inducible toxicity selectively toward bacteria by blue light (in contrast, silver nanoparticles demonstrate uncontrolled antibacterial effect all the time)
· hCQDs are designed for use with common polymers, they are soluble in organic solvents used for polymer dissolution
· hCQDs are not soluble in water- no degradation of the composite material by e.g biological fluids or in wet environment (in contrast, silver nanoparticles are water soluble and therefore exposure to water of biological fluid results in surface degradation upon time)
· General antibacterial mode of action- disruption of bacterial membranes by single oxygen- prevents antibacterial resistance
