Summary: In this study, IPN hydrogels with high flexibility and conductivity were prepared by modifying agar, oxidized alginate, and polyacrylamide. The presence of potassium and sodium ions in the modified agar and alginate chains endowed the hydrogels with conductive properties. These hydrogels exhibited strain-sensitive properties and can be used for detecting human motion. Furthermore, they maintained their flexibility and conductivity even after storing for six months.

Summary: Hydrogels, a class of hydrophilic polymers, have extensive water content and three-dimensional crosslinked networks. They have been widely used as plant culture substrates to overcome the drawbacks of hydroponics and soil. Many polysaccharide hydrogels with exceptional stability, high clarity, and low cost can be employed as plant substrates. However, the existing hydrogel-based plant growth substrates have not benefited much from the developments of gels in the past few decades. Prospects for future development include the creation of new conduction techniques, the development of potential new hydrogels, and the functionalization of hydrogels as plant culture substrates.

Summary: A liquid filament can separate into different shapes on a soft surface due to the interplay of inertial, capillary, and viscous forces. However, controlling the precise and stable morphological features of complex materials like soft gel filaments remains challenging. We propose a new method using thermally regulated instabilities to fabricate gel microbeads with precise control over their morphology and hydration state, resulting in topologically-selective microbeads.

Summary: Enzymatically active polysaccharide-based hydrogels and aerogels were developed using a thermostable beta-galactosidase enzyme embedded in nanoflowers. Commercial agar showed the most promising results in terms of reusability and enzymatic activity, outperforming unpurified agar and agarose. Commercial agar aerogels maintained integrity and enzyme protection, achieving similar hydrolytic activity as free enzymes and nanoflowers in hydrated form.

Summary: Intermolecular gelation of DNA and folic acid was observed in DMSO-water solution, forming a stable supramolecular hydrogel despite their similar net charge. The gel strength and gelation temperature were tunable, and the self-assembly process was systematically characterized using dynamic light scattering, small angle neutron scattering, rheology, and scanning electron microscopy. These soft gels formed of same polarity biopolymers in a milieu of strong electrostatic repulsion belong to a special class of soft matter not well studied in the past.

Summary: Super-paramagnetic iron oxide nanoparticles (SPIONs/Fe3O4) were synthesized in aqueous medium under a nitrogen atmosphere and made water-dispersible by cladding them with tannic acid (TA). The nanoparticles exhibited a size of around 15 nm and spherical morphology with negative surface charge. They showed super-paramagnetic nature and generated localized hyperthermia for cancer therapy, inhibiting cancer cell growth and causing cellular damage without noticeable innate toxicity.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
