“…Successful use of a biomaterial is possible after entrapment in biocompatible matrices, in which intactness and functional properties are fully preserved [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. One of the widely used approaches is sol–gel technology [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. During the synthesis, biopolymers are mineralized and hybrid structures with a nanosized inorganic component are formed [ 10 , 18 , 32 , 33 , 34 ].…”
