The adhesive property to the intestinal mucin of Bifidobacterium lactis LKM512, B. longum, B. breve, B. bifidum, B. adolescentis, B. infantis, Bacteroides vulgatus, Bacteroides distasonis, Eubacterium aerofaciens, Clostridium perfringens, Escherichia coli, and Lactobacillus acidophilus were examined. Adhesive rate of LKM512 to the mucin was significantly (p < 0.05, 0.01, or 0.001) stronger than the other strains from 2 to 100 time. Though the adhesive property of many strains was almost same to the mucin of 20-year-old and 50-year-old generations, in case of 4-month-old was different. Adhesive inhibitory effect of C. perfringens to the mucin by LKM512 was examined. Under the condition that LKM512 was 108/ml and that C. perfringens was 106/ml, adhesion of C. perfringens to the mucin was inhibited at 99.6%, when LKM512 adhered in advance. There was the strong inhibition of adhesion at 74.0%, when C. perfringens adhered to mucin in advance. Thus, LKM512 can inhibit the adhesion of harmful bacteria to the intestinal mucin, the possibility of using as a probiotic strain has to be verified.

Glassphalt suffers from performance defects, especially against moisture damage and fatigue cracking. In this research, the performance of glassphalt modified with CF has been evaluated against moisture damage, fatigue cracking and rutting. Based on this, Modified Lottman, Wilhelmy Plate (WP), Indirect Tensile Stiffness Modulus (ITSM), Indirect Tensile Fatigue (ITF), and Repeated Load Axial (RLA) tests have been performed on glassphalt modified with CF.

Polydopamine (PD), inspired by the wet adhesion mechanism of mussel foot proteins, has emerged as a promising adhesive material with wide-ranging applications. This study aimed to compare the adhesive properties of PD and Glass Ionomer Cement (GIC) on enamel and dentin substrates, evaluating PD's potential as an alternative adhesive in dental practice. A total of 120 human premolars were prepared, with 80 teeth allocated for Scanning Electron Microscopy (SEM) analysis and 40 teeth reserved for shear bond strength testing.

Challenges emerge in the quest for highly efficient and biocompatible coatings to tackle microbial contamination. Here, we propose a bioinspired paradigm combining (-)-epigallocatechin gallate (EGCG) and l-arginine surfactants (LAM) as all-green building blocks for advanced coatings with superior performance. Molecular dynamics simulations reveal the natural assembly process of the EGCG/LAM supramolecular nanoparticles (ELA NPs).

Polysaccharides, found universally in all living-species, exhibit diverse biochemical structures and play crucial roles in microorganisms, animals, and plants to defend against pathogens, environmental stress and climate-changing. Microbial exopolysaccharides are essential for cell adhesion and stress resilience and using them has notable advantages over synthetic polysaccharides. Exopolysaccharides have versatile structures and physicochemical properties, used in food systems, therapeutics, cosmetics, agriculture, and polymer industries.

Bacterial infections impede skin wound healing, and antibacterial hydrogels have garnered significant attention in the field of wound care due to their combined therapeutic effects. In this study, an intelligent, responsive AC-Gel@Cur-Au hydrogel was developed using temperature-sensitive agarose and pH-responsive chitosan as the structural framework, infused with Gel@Cur and AuNR. The AC-Gel@Cur-Au hydrogels demonstrated excellent mechanical properties, swelling capacity, tissue adhesion, and biodegradability.
