Majority current bone tissue biomimetics are based on collagen containing composites since the collagen is a
major organic component of the natural extra cellular matrix (ECM). Two main types of biomimetic composites, based
on: i) fibriliar or ii) electrospun collagen are in the focus of this review. It includes a brief presentation of the composition,
hierarchical structure and formation of natural bone, as a base of the bone biomimetic design strategy. Requirements to
substituting biomaterials (synthetic bone scaffolds and grafts) analogous to natural bone in terms of composition, structure
(at micro-, nano- or molecular level) and function are also included in this review.
