Sensors with autonomous self-healing properties offer enhanced durability, reliability, and stability. Although numerous self-healing polymers have been attempted, achieving sensors with fast and reversible recovery under ambient conditions with high mechanical toughness remains challenging. Here, a highly sensitive wearable sensor made of a robust bio-based supramolecular polymer that is capable of self-healing via hydrogen bonding is presented. The integration of carbon fiber thread into a self-healing polymer matrix provides a new toolset that can easily be knitted into textile items to fabricate wearable sensors that show impressive self-healing efficiency (>97.0%) after 30 s at room temperature for K/Na sensing. The wearable sweat-sensor system-coupled with a wireless electronic circuit board capable of transferring data to a smart phone-successfully monitors electrolyte ions in human perspiration noninvasively in real time, even in the healed state during indoor exercise. Our smart sensors represent an important advance toward futuristic personalized healthcare applications.

Owing to the rapid advancement of wearable electronics and soft robotics, anti-swelling hydrogels have attracted considerable interest for underwater motion sensing because of their outstanding stability under aqueous conditions. Herein, this review first catalogues polysaccharide-based building blocks employed to engineer anti-swelling hydrogels, then systematically discuss structural design strategies and review recent advances in their application to motion sensing. This review first summarizes the use of natural polysaccharides-including chitosan and sodium alginate-for preparing anti-swelling hydrogels.

In this study, nanocellulose (NC) was produced via ultrasonication of supramolecular chemistry-driven delignified softwood with thymol and methanesulfonic acid-based solvent. Supramolecular chemistry-driven delignification could be performed under very mild conditions (40 °C-60 °C for 1-5 min), allowing the production of cellulosic pulp (CP) with low lignin content to take place with very low energy consumption. Due to the mild conditions, CP with good optical properties (high whiteness) was obtained.

This study successfully demonstrates a new concept of complementary electrostatic interactions between drugs and nanocarriers. Water-soluble modified chitosan (Na-CMC) has negatively charged carboxylate groups on its side chains and co-assembles with the positively charged anticancer agents rhodamine 6G (R6G) or doxorubicin (DOX). This concept represents a promising facile strategy for the development of efficient, multifunctional drug delivery systems to potentially enable safer, more effective chemotherapy.

Bio-based polyurethanes are promising sustainable elastomers whose polymeric network structure has a decisive impact on their properties. However, existing bio-based polyurethanes face challenges in simultaneously enhancing mechanical strength and toughness. Inspired by the multilevel heterogeneous structure of articular cartilage, we propose a bionic design strategy of rigid-flexible coupled supramolecular cross-linking networks to prepare bio-based polyurethane elastomers with enhanced strength and toughness.
