The present technique pertains to a method of preparation of a succinylated collagen-fibrinogen hydrogel and a succinylated collagen-fibrinogen hydrogel prepared thereby. The method of preparation of a succinylated collagen-fibrinogen hydrogel according to the present technique can produce a collagen-based bio-substance in a simple process, wherein collagen can be prevented from being entangled and an improvement can be brought about in hydrophilicity, cell growth rate, cell compatibility, and cell diffusion capability, whereby the collagen-based bio-substance exhibits excellent biocompatibility in vivo.

The present invention is a composition that can form an edible film or an edible liquid coating that can be applied to the surface of fresh fish (fillets or cuts) or fresh seafood. The present invention acts as a physical barrier preventing oxygen, water and microorganisms from entering the food product, and also acts as a bacteriostatic and antioxidant agent.

Provided are an injectable intraocular microgel and an injectable intraocular hydrogel that are safe to a human body and that can release a drug in the eye for a long period of time. This injectable intraocular microgel may have a form in which a drug is loaded on a hyaluronic acid microgel generated by causing hyaluronic acid copolymers to cross-link with each other through a w/o emulsion method.

Implantable bone compositions are provided. The implantable compositions comprise hydratable bone putties. The hydratable bone putties comprise porous ceramic granules having an average diameter from about 50 μm to 800 μm and the composition has a texture value above about 1000. The porous ceramic granules comprise hydroxyapatite and beta-tricalcium phosphate. The implantable bone compositions further include collagen carriers. In some embodiments, the hydratable bone putty can be hydrated to form a non-settable flowable cohesive cement or gel. Methods of making and using the implantable compositions are also provided.
