“…Protein-based hydrogels are of paramount importance in the biomedical field [1][2][3][4][5]. They combine biocompatibility, biodegradability and high hydration with the ability to present specific amino acid sequences that can be recognized by cells to favor their adhesion, proliferation and differentiation [6][7][8][9][10].…”

Type I collagen and fibrin are two essential proteins in tissue regeneration and have been widely used for the design of biomaterials. While they both form hydrogels via fibrillogenesis, they have distinct biochemical features, structural properties and biological functions which make their combination of high interest. A number of protocols to obtain such mixed gels have been described in the literature that differ in the sequence of mixing/addition of the various reagents. Experimental and modelling studies have suggested that such co-gels consist of an interpenetrated structure where the two proteins networks have local interactions only. Evidences have been accumulated that immobilized cells respond not only to the overall structure of the co-gels but can also exhibit responses specific to each of the proteins. Among the many biomedical applications of such type I collagen-fibrin mixed gels, those requiring the co-culture of two cell types with distinct affinity for these proteins, such as vascularization of tissue engineering constructs, appear particularly promising.

Nowadays, sensor devices are developing fast. It is therefore critical, at a time when the availability and recyclability of materials are, along with acceptability from the consumers, among the most important criteria used by industrials before pushing a device to market, to review the most recent advances related to functional electronic materials, substrates or packaging materials with natural origins and/or presenting good recyclability. This review proposes, in the first section, passive materials used as substrates, supporting matrixes or packaging, whether organic or inorganic, then active materials such as conductors or semiconductors. The last section is dedicated to the review of pertinent sensors and devices integrated in sensors, along with their fabrication methods.

“…[ 8 ] Ascribing to the strong binding between metal ions and organic groups, the sol‐gel transition often depends on external conditions, such as temperature, pH value, and redox reactions. [ 9 ] Noticeably, the effective integration of ions into hydrogel network is still a profound challenge.…”

Inspired by biological camouflage strategy according to the surrounding environment, a facile method to fabricate state‐switchable cellulose hydrogels (fluid, brittle, and rigid hydrogel) driven by Ca2+/Zn2+ ion exchange is reported. The high content of Ca2+ ions leads to the formation of a rigid hydrogel (Gel‐H‐Ca2+) with a great compressive strength (≈2.2 MPa) through coordination cross‐linking network, while Zn2+ ions give the cellulose (Sol‐L‐Zn2+) a fluid state by eliminating the cellulose intermolecular connections, making it possible to obtain injectable and healable hydrogels. Gel‐H‐Ca2+ is highly oriented and anisotropic, and such flexible hydrogel can effectively monitor slight bending and pressure changes of fingers. This cellulose hydrogel will be a promising candidate for bionic and multifunctional sensors.
