Summary: A double-layer coating strategy using tannic acid and enteric L100 was reported to encapsulate probiotics for improved delivery in the gastrointestinal tract. The encapsulated Escherichia coli demonstrated enhanced survival and proliferation capabilities, leading to superior efficacy against colitis. This spatiotemporal delivery method shows promise in enhancing the therapeutic efficacy of bacteria-based therapy for GI tract-related diseases.

Summary: This study investigates the influence of surface physicochemistry on bacterial attachment and detachment under flow through empirical and simulation studies. The results show that different materials have similar effects on the number of attached bacteria, but the number of residual bacteria after detachment varies, which is determined by the interfacial physicochemistry.

Summary: This research evaluated the heat inactivation kinetics of five bacterial spores and found that the presence and magnitude of shoulders depended on the bacterial spore species and varied with treatment temperature in the same proportion of traditional D-T values. An equation which included the constant Sl/D-T was proposed as a result.

Summary: Motivated by the thermal phase transition mechanism of gelatin, a Janus supramolecular hydrogel dressing with skin temperature-triggered adhesion has been synthesized. This hydrogel exhibits asymmetric and controllable adhesion, excellent mechanical performance, antibacterial activity, and biocompatibility. With a high wound healing efficiency of 98.45%, it has huge potential for wound management and treatment.

Summary: This study presents a kirigami-inspired approach to control adhesion with high directional asymmetry. By inscribing a specially designed labyrinth pattern in an adhesive film, the adhesion is enhanced in a specific direction while easy detachment is achieved in the opposite direction. This mechanism can be further enhanced by using different materials and structures.

Summary: This work focuses on quantifying the conditions for detachment of inclined oblate spheroids in slow viscous flow, which significantly influences colloidal transport in porous media. The impact of orientation angle on hydrodynamic moment, adhesive DLVO force, contact area, and critical detachment velocity was systematically evaluated through numerical and laboratory studies. The methodology developed for producing stretched latex polystyrene particles reduces the geometric uncertainty of nonspherical fines and determines the geometry of oblate spheroids using semi-major and semi-minor axes. The explicit formula derived for the detaching velocity of inclined attached particles provides insights into the detachment process in porous media.

Summary: This study presents a method for switchable adhesion between hydrogels by inducing wrinkles through a mechanical process, allowing for enhanced and weakened adhesion, as well as easy detachment. The approach demonstrates a proof-of-concept hydrogel patch that can strongly adhere to and gently detach from a damaged hydrogel device based on the switchable hydrogel adhesion.

Summary: The emergence of drug-resistant bacteria has led to the need for novel approaches and targets to combat this challenge. Bacterial two-component systems (TCSs) are important in bacterial adaptive responses and are linked to antibiotic resistance and virulence. A study developed maleimide-based compounds and evaluated them against a model histidine kinase, resulting in the identification of a molecule that decreased the lesion size caused by methicillin-resistant S. aureus skin infection by 65% in a murine model.

Summary: This study examined the effects of voltage and oxygen on bacterial inactivation in water using pulsed dielectric barrier discharge under atmospheric pressure. The results showed that there was a minimum voltage requirement for inactivating E. coli and S. typhi samples, with significantly higher inactivation rates observed with the presence of oxygen.

Summary: Fatty acids show promise as antipersister and antibiofilm agents, with medium-chain saturated fatty acids such as undecanoic acid and lauric acid being particularly effective at inhibiting persister cell formation in E. coli and enterohemorrhagic E. coli. These fatty acids not only repress persister formation but also reduce biofilm formation, demonstrating their potential for treating bacterial infections.

Summary: The study investigated the anti-biofilm activities of colicins E1, E2, and E3 using cell-free protein synthesis, identifying E2 with DNase activity as the most effective at killing target biofilm cells while leaving non-targeted biofilms unharmed. Engineered probiotic Escherichia coli organisms were able to synthesize and secrete colicin E2, inhibiting biofilms and killing preformed indicator biofilms. These findings suggest the potential of using engineered microorganisms to produce antimicrobial colicin proteins as a therapeutic strategy for biofilm-associated infections.

Summary: Reverse electrodialysis (RED) is an effective method for generating electricity by mixing different salt concentrations in water using cation-exchange membranes (CEM) and anion-exchange membranes (AEM). In this study, a procedure for fabricating a RED device using laboratory-scale CEM and AEM for power production is demonstrated. The article also includes the explanation of measurement conditions, net power output calculation, fundamental parameters, and theoretical parameters affecting overall cell performance.
