Abstract:

BioNanoGum project proposal aims to develop an innovative biogenic nano-system for resolution of dysbiosis oral biofilms and inflammation involved in gingivitis and periodontitis, based on an innovative bacterial nanocellulose - fungal (nano)chitosan stimuli-responsive hydrogel, biogenic selenium nanoparticles (bioSeNPs), and hollow pollen shells filled with biogenic silica nanoparticles (bioSiOxNPs). Gingivitis and periodontitis affect more than 30% of globe population and can lead to teeth loss, but also other complications and severe diseases (Alzheimer, diabetes, autoimmune diseases). SeNPs, silicic acid released from SiOxNPs, and chitosan nano-structures determine (frank) resolution of dysbiosis biofilms and inflammation. However, there are also several drawbacks such as a very narrow physiological window (in the case of Se), or induced inflammation through a MAMPs similar mechanism, mediated by the Toll-like receptors (in the case of SiOxNPs). New formulations are needed in order to reduce risks of negative effects and to optimize the beneficial effects. BioNanoGum will use compounds acting complementary to SeNPs, which will lead to the reduction of Se dose. The pollen shells, obtained by Kombucha fermentation, will be used as encapsulation carriers for SiOxNPs, which allows bearing benefits from the anti-inflammatory, anti-bacterial and wound-healing effects of the silicic acid slowly released from bioSiOxNPs. The biogenic nano-system will deliver different components into a complementary manner and will act both on the resolution of pathogenic biofilms and on that of inflammation. BioNanoGum involves the niche between biotechnology and nanotechnology with health applications. This niche market has a significant growing potential, because it addresses several of the main health problems in the European Union and worldwide, from the beginning of the 21st century : an ageing population, with an increased incidence of non-communicable / chronic disease.
