Marine Spongin: Naturally Prefabricated 3D Scaffold-Based Biomaterial [PDF]

Marine Drugs, 2018
The biosynthesis, chemistry, structural features and functionality of spongin as a halogenated scleroprotein of keratosan demosponges are still paradigms. This review has the principal goal of providing thorough and comprehensive coverage of spongin as a

3D Spongin Scaffolds as Templates for Electro-Assisted Deposition of Selected Iron Oxides

Biomimetics
The skeletons of marine sponges are ancient biocomposite structures in which mineral phases are formed on 3D organic matrices. In addition to calcium- and silicate-containing biominerals, iron ions play an active role in skeleton formation in some ...

Rapid Hemostatic Biomaterial from a Natural Bath Sponge Skeleton

Marine Drugs, 2021
Uncontrolled bleeding is the main cause of mortality from trauma. Collagen has been developed as an important hemostatic material due to its platelet affinity function. A bath sponge skeleton is rich in collagen, also known as spongin.
