... In line with the pursuit of environmentally friendly alternatives, recent developments in multifunctional chitosan-based tanning agents derived from biomass, such as enoki mushroom roots, have demonstrated significant potential in reducing the environmental impact of traditional leather tanning processes. These agents offer chrome-free tanning solutions with excellent tanning, dyeing, and antimicrobial properties, while simplifying the tanning process and minimizing wastewater pollution [14]. The sustainability assessment, including LCA and efficiency indicators, demonstrated that the optimized design outperformed the base case regarding water management, process efficiency, and sustainability footprint despite slightly higher costs associated with the water regeneration network installation. ...

... Therefore, Bio-inspired synthesis is a promising approach to overcoming obstacles owing to nature's diversity [206]. Biopolymers are produced through chemical synthesis or fermentation from bioresources [207]. The process of directly extracting biopolymers from bioresources such as cellulose, lignin, lipids, proteins, and starch is known as biopolymer extraction [208,209]. ...

... The sensing and transformation process of skin-like sensors relies on measuring a range of electrical properties such as resistance, capacitance, voltage, and impedance. 72 For instance, wearable temperature sensors based on various sensing mechanisms such as resistance changes induced by thermal expansion, 73 capacitance changes induced by alterations in dielectric constants, 74,75 and the thermochromic effect and more, 76,77 have been developed. These temperature sensors are crucial for monitoring physiological activities as temperature is a fundamental parameter. ...

... In the field of food safety, meat spoilage is a serious problem today. Extended storage of meat can lead to microbial enzymatic reactions, specifically the decarboxylation of amino acids and the amination of chemical molecules containing carbonyl groups [2]. Thus, the degradation of food can be easily recognised by detecting NH 3 . ...

... Furthermore, some other "X-in-one" post-tanning processes including retanning, filling, dyeing, and fatliquoring have been proposed and investigated. For instance, acrylic acid (AA), diallyl dimethyl ammonium chloride (DMDAAC), dodecyl acrylate (DA), and 1,8-naphthalic anhydride (NA), were employed to prepare an amphoteric polymer (labeled as pADD-DMENA) for successfully achieving the high-performance retanning, fatliquoring, and dyeing of Cr-free organic tanned leather [28]. The pADD-DMENA treated leather had a bright yellow color surface with high uniformity, superior lightfastness, durability, and washability. ...
