“…1a) is known for its excellent biocompatibility (Shi et al, 2014). It makes BC hydrogels a potential material for various bioengineering applications, such as implant replacement of human tissues (Malm et al, 2012;Wang et al, 2010;Zang et al, 2015), encasement for tissue regeneration (Bäckdahl et al, 2006;Bäckdahl et al, 2008;Gibas and Janik, 2010;Kowalska-Ludwicka et al, 2013), etc. From a structural point of view, BC hydrogel is a typical nonwoven bio-material.…”
