“…[87,88] For chemical approach, an active cross-linker agent is usually requisite for gelation, which is necessary to make covalent bonds that connect polysaccharide or its composites to their polymeric molecules witin the 3D hydrophilic scafolds. Most commonly focused cross-linkers are epichlorohydrin, [89,90] N,N0 -methylenebisacrylamide, [84,85] citric acid, [91] polyethylene glycol diacrylate, [92] 1,3-diaminopropane, [93] and glutaraldehyde, [89] genipin [94] etc. The formation of polymeric hydrogels through chemical approaches could be accomplished using relevant irradiation, for example gamma rays, [95] electron beams, [96] and ultraviolet radiation.…”

Biopolymers are considered as a favorable group of substances with a broad array of applications, of which biomedical field stands out. The interesting features of biopolymers such as low‐cost, non‐cytotoxicity, hydrophilicity, biodegradation and biocompatibility make them promising and excellent feedstock to be used in implantable devices. The bounteous reactive functional groups in the backbone structure of polysaccharides and its derivatives could be utilized to develop hydrogels, nano‐composite and 3D scaffolds with appealing structures and desired features, leading to promising research attention towards biomedical fields. The present review describes the foremost properties as well as potential of different biopolymers, and their composites for application in implantable biomedical systems. This work may introduce readers about the comprehension of state‐of‐the‐art advances, real present challenges along with the future anticipation of eco‐friendly and biomimetic techniques for the modification of biopolymeric materials to improve their biomedical applications.

The eco-sustainable use of materials derived from agricultural and food processing waste will represent one of the most stimulating challenges shortly. Chitin and chitosan are two remarkable examples of how molecules with high added value can be extracted from food waste, such as crustaceans’ shells, fungi, mollusks, etc. This Perspective summarizes the current state of knowledge about chitin extraction, chitosan production, and hydrogel formation, highlighting the environmental critical steps in the common route (use of strong acids and basis, toxic solvents, and not eco-friendly crosslinkers). At the same time, promising green alternatives are described and analyzed. Examples are the employment of NADESs or DESs (such as choline chloride: urea or choline chloride: organic acids mixtures) for chitin extraction and dissolution, use of citric acid both in chitin extraction and hydrogel formation or utilization of natural extracts, like genipin, as green cross-linkers under mild conditions (heating at 37 °C for 12 h). In particular, this perspective aims to provide a stimulating basis for the development of processes based on the recycling and reusing of chemicals, during the different preparation steps, in line with “system chemistry” and “circular economy” principles.
