“…Oscillatory rheological properties of prepared hydrogels with different polymer concentrations were investigated by controlling variables. 17 Briefly, the variation curves of storage modulus (G′) and loss modulus (G″) were obtained under multifrequency, dynamic strain, and continuous temperature changes. To explore gel injectability, a timedependent rheology measurement of optimal precursor solution was conducted at 37 °C by applying a strain of 1% at an angular frequency of 10 rad/s.…”

Probiotics were found to be effective in ameliorating the microbial dysbiosis and inflammation caused by intestinal pathogens. However, biological challenges encountered during oral delivery have greatly limited their potential health benefits. Here, a model probiotic (Lactobacillus rhamnosus) was encapsulated in an intestinal-targeted hydrogel to alleviate bacterial enteritis in a novel mode. The hydrogel was prepared simply by the self-cross-linking of thiolated hyaluronic acid. Upon exposure to H 2 S which were excreted by surrounding intestinal pathogens, the hydrogel can locally degrade and rapidly release cargos to compete with source pathogens in turn for binding to the host. The mechanical properties of hydrogel were studied by rheological analysis, and the ideal stability was achieved at a polymer concentration of 4% (w/v). The morphology of the optimal encapsulation system was further measured by a scanning electron microscope, exhibiting uniform payload of probiotics. Endurance experiments indicated that the encapsulation of L. rhamnosus significantly enhanced their viability under gastrointestinal tract insults. Compared with free cells, encapsulated L. rhamnosus exerted better therapeutic effect against Salmonella-induced enteritis with negligible toxicity in vivo. These results demonstrate that this redox-responsive hydrogel may be a promising encapsulation and delivery system for improving the efficacy of orally administered probiotics.

“…10 Intriguingly, the photodimerization yields dramatically drop in DNA duplexes and in RNA strands. 3,6,11 Experimental studies demonstrated that irradiation around 260 nm leads to the formation of two different types of adenine dimers AA* and AA (Figure 1) and suggested that they have a common azetidine intermediate. 5 Here, we report the first theoretical study exploring the excited state pathways that lead to the azetidine precursor.…”

“…Rheometer (TA, NETZSCH-Geraẗebau GmbH) was used to investigate the rheological characteristics of SGCA hydrogels. 16 At 25 °C, the hydrogel samples were mounted on a rheometer plate with a diameter of 20 mm and spacing of 1.0 mm. Strain correlation measurements were carried out to determine the linear viscoelastic region of the hydrogels (the linear viscoelastic region was 0.1−100 Pa, the fixed frequency was 1.0 Hz, and the strain scanning range was 0.01−100%).…”

Silver nanoparticles (AgNPs) are broad-spectrum antibacterial agents that are safe for the environment and the human body. To achieve a balance between material functionality, degradability, and safety of AgNPs, the peanut red skin (PSE)/polyphenol-hydroxypropyl-β-cyclodextrin (HPβCD)/AgNPs were prepared for the first time by ultrasound-triggered molecular encapsulation and biosynthesis for hydrophilic fusion of medicine and small molecules. Additionally, a novel “controlled release” sodium alginate (SA)-based hydrogel was developed and medicine/small-molecule self-assembled PSE/HPβCD/AgNPs were introduced into the three-dimensional network structure of the SA hydrogels. The SA-based hydrogels exhibited excellent mechanical and rheological properties. In different pH conditions, the hydrogels exhibit differing release and expansion behaviors, and the maximum cumulative release of AgNPs was 98.21% at pH > 6.8. Furthermore, the hydrogels exhibited strong antibacterial effects against pathogenic bacteria. They also showed excellent antioxidant properties and cytocompatibility. These advantages highlight the potential utility of the developed hydrogels for biomedical applications and agricultural fields.
