Nanofibrills filters for environmental nanoparticles: Development of innovative protection against Nano-pollution

Tildelt: kr 6,1 mill.

Nanopollution is a generic name for all waste generated by nanodevices, during the nanomaterials manufacturing process or unintentionally by incineration of normal products or nanoproducts. This kind of waste may be very dangerous because of its size and persistence. Most human-made nanoparticles do not appear in nature, so living organisms may not have appropriate means to deal with nanowaste. The normal health defence is passed over. NFC are the building blocks of fibres, just like the fibres are the bu ilding blocks of the trees. Their unique mechanical characteristics, the relatively high availability and being renewable makes them the perfect material to create filters for nanoparticles. The research wants to verify the efficiency of filtration of a n anostructured cellulose filter against nanoparticles. The project will be organized in work packages: WP-1: Nanofilters production, WP-2: Filtration tests and WP-3: Toxicology tests. WP1 main tasks will be: 1.1 Produce a set of fibril qualities varying in surface chemistry and morphology 1.2 Develop an NFC based filter for nanoparticles, 1.3 Characterization of filters by microscopy (pores), gas transmission tests, strength tests and other relevant tests 1.4 Describe the influence of substrate morpholog y, density and surface chemistry on filtration and diffusion properties, 1.5 Describe the interaction between filter and nanoparticles (Physical and Chemical). WP2 main tasks will be: 2.1 Production of organic, inorganic and polymeric nanoparticles, 2.2 Implementation of the filtering system with the NFC based filter, 2.3 Measurement of filtration efficiency, 2.4 Morphological characterization of filters and nanoparticles. WP3 main tasks will be: 3.1 Toxicological tests on NFC water dispersion 3.2 CE cytotoxicological tests on filters.
