Filter made entirely with natural and biodegradable materials, for the protection of the respiratory tract of patients in the medical-surgical field and process for making it. The filter has a porosity or 80-98% and pore diameters of 100-350 micrometers and the pores have a shape of channels open at the ends, which are parallel to each other. The filter is obtained by preparing an aqueous solution of chitosan and an aqueous solution of gelatin, mixing them, pouring it into a container, keeping the container closed until obtaining a hydrogel and freeze-drying. A cross-linking step takes place by (a) adding a chemical cross-linker to the mixture of the chitosan and gelatine solutions and cross-linking before freeze-drying, or (b) subjecting the freeze-drying product to a thermal dehydration treatment.

Filter for the exchange of heat and moisture for application in the medical field and procedure for the production thereof

The present invention relates to a composition for the protection against solar radiation, consisting of an organic matrix, preferably a gelatin, and hydroxyapatite nanoparticles modified by the substitution of part of the phosphorus with titanium, and part of the calcium with iron.

Physical solar filter consisting of substituted hydroxyapatite in an organic matrix

The present invention relates to hydroxyapatite doped with Feions and Feions which partially substitute the calcium ions in the crystal lattice. The hydroxyapatite is characterized by an intrinsic magnetism of 0.05 to 8 emu/g, measured by applying a magnetic field of 34 Oe, due to the presence of magnetic nano-domains in the crystal lattice of HA, given the limited amount of magnetic secondary phases present, less than about 3% by volume. The intrinsically magnetic hydroxyapatite can be loaded with biological substances selected in the group consisting of proteins, genes, stem cells, growth factors, vascularization factors, active substances and drugs, under the control of an external magnetic field, as a carrier and release agent for biological substances or drugs, as a contrast agent in diagnostics or for bone or osteocartilage regeneration.
