“…Alginate-and chitosan-based hydrogels are some of the more widely studied bio-adsorbents for such application [153][154][155][156][157]. Indeed, as three-dimensional cross-linked polymer networks, hydrogels can absorb large amounts of water, increasing the possibilities and efficiency of interactions between the functional groups of the adsorbent and the targeted soluble substances.…”

“…It has been shown that alginate-based cross-linked beads are able to remove relatively high amounts of toxic metal ions and cationic dyes [153]. In particular, this biomaterial possesses ultrahigh adsorption capacity for methylene blue and methylene violet dyes (respectively, 2977 and 2105 mg/g) as well as for Pb 2+ ions with a maximum capacity of 2042 mg/g.…”

The review covers recent literature on the ocean as both a source of biotechnological tools and as a source of bio-inspired materials. The emphasis is on marine biomacromolecules namely hyaluronic acid, chitin and chitosan, peptides, collagen, enzymes, polysaccharides from algae, and secondary metabolites like mycosporines. Their specific biological, physicochemical and structural properties together with relevant applications in biocomposite materials have been included. Additionally, it refers to the marine organisms as source of inspiration for the design and development of sustainable and functional (bio)materials. Marine biological functions that mimic reef fish mucus, marine adhesives and structural colouration are explained.

“…The spectrum of SA at 1640, 1715 and 942 cm -1 . wavenumbers were C=O and O-Na in -COONa group, respectively [43,44]. Furthermore, the stretching vibration peaks emerged near 1382 and 950 cm -1 were -OH radical in-plane and out-of-plane vibrations exhibit a characteristic spectrum.…”

“…As the reaction continued, a robust capsule with Semi-IPNs structure was produced due to the Ca 2+ uninterruptedly coupled with -COOin G unit of SA via chelating and covalent bonding. And at this moment, the O-Na (937 cm -1 [42][43][44]) disappeared ( Figure 3a). The hydrophilic functional groups (hydroxyl groups and carboxyl groups, etc.)…”

“…The FT-IR spectra and formation principle of the prepared capsules were shown in Figure 3. The visible hydrogen bonding stretching vibration peak located in 3150~3300 cm -1 intervals were caused by -OH and -COOin the chain of SA interacting with each other (Figure 3a) [42,43]. The -CH 3 and -CH 2 vibration peaks were observed around 29203 050 cm -1 .…”

Responsive thermochromic fiber materials capable of miniaturization and integrating comfortably and compliantly onto the soft and dynamically deforming human body are promising materials for visualized personal health monitoring. However, their development is hindered by monotonous colors, low‐contrast color changes, and poor reversibility. Herein, full‐color “off–on” thermochromic fluorescent fibers are prepared based on self‐crystallinity phase change and Förster resonance energy transfer for long‐term and passive body‐temperature monitoring, especially for various personalized customization purposes. The off–on switching luminescence characteristic is derived from the reversible conversion of the dispersion state and fluorescent emission by fluorophores and quencher molecules, which are embedded in the matrix of a phase‐change material, during the crystallizing/melting processes. The achievement of full‐color fluorescence is attributed to the large modulation range of fluorescence colors according to primary color additive theory. These thermochromic fluorescent fibers exhibit good mechanical properties, fluorescent emission contrast, and reversibility, showing their great potential in flexible smart display devices. Moreover, the response temperature of the thermochromic fibers is controllable by adjusting the phase‐change material, enabling body‐temperature‐triggered luminescence; this property highlights their potential for human body‐temperature monitoring and personalized customization. This work presents a new strategy for designing and exploring flexible sensors with higher comprehensive performances.
