Abstract: A novel approach in cancer therapy based on the cytotoxic effect of silver nanoparticles on cancer cells, without any deleterious effect on normal cells, has been developed.
Process for the production by plasma of nanometric thickness coatings allowing controlled release of silver ions of other elements, or of molecules of biomedical interest, from solid products, and products thus coated, R. D’agostino, P. Favia, F. Fracassi, E. Sardella, C. Costagliola, A. Mangone. Patent WO2013021409-A1: E. Sardella, P. Favia et al. WO2013021409 (2013)
Abstract: Process for the production by plasmochemical deposition of a film having a nanometric thickness, optionally multilayered, permitting carrying out in a controlled, uniform and long lasting way, release of substances of interest in a surrounding medium containing liquids, from a substrate including the substance to be released as micro/nano particles, or from a layer deposited on the substrate including the substance to be released as micro/nano particles, or from a layer of the substance to be released deposited on the substrate, or from a substrate that is the substance to be released optionally in the form of particles. The substances to be released can be metals, compounds having anti-bacterial properties, biologically active molecules such as drugs, hormones, vegetable extracts, peptides, lipids, protides and glucides. The layer with the substance to be released, be it organic or inorganic, is obtained by plasmochemical deposition optionally having a structure similar to polyethylene oxide (PEO) or polyethylene glycol (PEG), called PEO-like polymers, constituted, in a variable percentage da ethylene oxide units (-CH2CH2O-, EO); barrier film is obtained by depositing by plasma at least one organic or inorganic layer, optionally with a PEO-like structure, wherein chemical composition, degree of crosslinking and thickness are adjustable by the plasmo chemical deposition process parameters, and allow to adjust the release of the active substance according to specific needs. The structures on which the above said films can be deposited are: medical-surgical devices, common handworks, structures known as scaffolds, and the above defined substances to be released themselves. The invention also relates to medical-surgical devices, common handworks and scaffolds coated by a substrate and barrier layer, as well as to biologically active substances coated by at least one barrier layer.
Synthesis of nano-sized CaCO3 particles by spray dryer. Ciccarella, V. Vergaro. EP2796412 (A1) (2013).
Abstract: Method for preparing calcium carbonate comprising the steps of mixing an aqueous solution of NaHCO3 and an aqueous solution of CaCl2 , then atomizing them in a pre-heated air flow, thereby obtaining calcium carbonate in powder form and sodium chloride. The calcium carbonate obtained comprises nanoparticles smaller than 100 nm.
