“…The year 2000 could be considered as the "starting point" in this field. Research for obtaining new types of bio-nanocomposites based on collagen in solid physical forms of matrices or membranes in which inorganic components can be hydroxyapatite, biovitroceramica, TiO 2 , SiO 2 , natural layered silicate as it is or modified with hydrolysed collagen, antioxidants has developed (Ficai et al 2010a;Albu et al, 2009;Baia et al, 2008;Piticescu et al, 2008;Potarniche et al, 2010;Vuluga et al, 2007;Vuluga et al, 2008a). Organic compounds that can interact with collagen are represented by a series of biological active substances or other biocompatible polymers, their compatibility being previously tested with collagen gel or colloidal solutions.…”
