Gecko-inspired smart photonic crystal films with versatile color and brightness variation for smart windows

Hanwen Huang et al.

Summary: Reptiles like geckos use a combination of structural and pigmentary elements to create versatile colors and modulate skin brightness. Researchers have integrated thermochromic pigments and viologen-based electrochromic materials into colloidal photonic crystals for the first time, producing multiresponsive and large-sized photonic crystal films. These films can display RGB colors under different temperatures and adjust color brightness in response to external electric fields, mimicking the color variation abilities of geckos.

Fabrication of intelligent pH-sensing films with antioxidant potential for monitoring shrimp freshness via the fortification of chitosan matrix with broken Riceberry phenolic extract

Fredrick Nwude Eze et al.

Summary: A versatile colorimetric indicator film based on chitosan and broken Riceberry phenolic extract was developed, showing enhanced physical and mechanical attributes. The CHI-RPE films exhibited increased hydrophobicity, mechanical resistance, thermal stability, barrier properties, and antioxidant activity compared to plain CHI film. Notably, the CHI-RPE film also produced intense naked-eye detectable colorimetric response to pH variation and volatile ammonia, making it a promising option for on-site visual detection of freshness in seafood products.

Anthocyanins-loaded nanocomplexes comprising casein and carboxymethyl cellulose: stability, antioxidant capacity, and bioaccessibility

Huijun Cui et al.

Summary: This study aimed to prepare nanocomplexes through self-assembly of casein and carboxymethyl cellulose to encapsulate and stabilize ACNs. Different adding sequences of raw materials influenced the particle size and encapsulation efficiency of nanocomplexes, which in turn affected their protection of ACNs. Complex II showed the best stability and antioxidant capacity among the three types of nanocomplexes formed in this study.

Development of pH-responsive absorbent pad based on polyvinyl alcohol/ agarose/anthocyanins for meat packaging and freshness indication

Yue He et al.

Summary: Absorbent pads with antioxidant and pH-responsive color changing functions were developed for fresh keeping and freshness indication of meat. The pads showed improved strength and DPPH radical scavenging activity with increased PSPA content, but reduced swelling ratio. The color of the pads changed significantly with pH, and the pad containing 9% PSPA exhibited the most distinguishable color change. The pad served as an active packaging for minced meat, indicating real-time spoilage and extending shelf life by at least 24 h.

Improving emulsifying properties of carboxylated microcrystalline cellulose by calcium bridging to hydrophobic peptides

Feiyang Li et al.

Summary: This study enhanced the emulsifying properties of microcrystalline cellulose through carboxylation and bridging treatment. Ca2+ bridging significantly altered the particle characteristics of CC-Ca-HP, leading to improved emulsifying stability. The formed network structure in the CC-Ca-HP emulsion contributed to the release of fatty acids, increased bioaccessibility of zeaxanthin, and reduced oil oxidation.

Thiazolo thiazole based cross-linker to prepare highly fluorescent smart films with tunable emission wavelength and their multi-responsive usage

Zeynep Dikmen et al.

Summary: A new molecule, HPhTT, was synthesized and used as a cross-linker in the preparation of highly fluorescent and intelligent PVA-based films, with emission wavelength and photoluminescence intensity being strongly influenced by dye and base concentrations. The films exhibited highly sensitive halochromic properties against acids and bases, while also showing responsiveness to metal cations. The unique films demonstrated potential as chemosensors and could undergo reversible color changes and shifts in emission wavelength upon treatment with specific solutions.
