====Nanofiber self-assembly====
Molecular self-assembly is one of the few methods for creating biomaterials with properties similar in scale and chemistry to that of the natural ''in vivo'' extracellular matrix (ECM), a crucial step toward tissue engineering of complex tissues.<ref name="cassidy">{{cite journal | vauthors = Cassidy JW | title = Nanotechnology in the Regeneration of Complex Tissues | journal = Bone and Tissue Regeneration Insights | volume = 5 | pages = 25–35 | date = November 2014 | pmid = 26097381 | pmc = 4471123 | doi = 10.4137/BTRI.S12331 | url = https://www.repository.cam.ac.uk/bitstream/1810/247086/1/Cassidy%202014%20Bone%20and%20Tissue%20Regeneration%20Insights.pdf }}</ref> Moreover, these hydrogel scaffolds have shown superiority in <!-- not a mistake -->in vivo toxicology and biocompatibility compared to traditional macro-scaffolds and animal-derived materials.
