The immune system is an especially appealing target due to its involvement in many different diseases, and ex vivo-engineered immune cell therapies like chimeric antigen receptor (CAR) T therapy have already demonstrated remarkable clinical success in certain blood cancers. Although gene delivery can potentially address some of the cost and manufacturing concerns associated with current autologous immune cell therapies, transfecting immune cells in vivo is challenging. Not only is extrahepatic NP delivery to lymphoid organs difficult, but immune cells like T cells have demonstrated particular resistance to transfection.

While topological materials often possess fragile surface states, trivial topological materials not only offer a larger pool of candidates but also demonstrate robust surface states. As a result, the search for topological catalysts has expanded to include trivial schemes. In this study, a novel 2D Janus monolayer, MoSMg, which demonstrates exceptional obstructed atomic insulating behavior, is presented. Crucially, this trivial metallic topological state exhibits clean obstructed surface states, leading to a significant enhancement in catalytic performance for the HER in electrochemical processes, particularly under high hydrogen coverage. Moreover, the edge sites of this MoSMg monolayer exhibit even more superior catalytic activity, characterized by near-zero Gibbs free energies.

This article presents a study of a novel carbon–cellulose-based paste intended for screen printing RF devices. The investigation specifically explores the application of high-reactivity carbon mixture (HRCM) particles as conductive fillers. The results demonstrate that optimal electrical conductivity values and discrete electromagnetic dipole performances can be achieved at lower concentrations of solid conductive material compared to conventional pastes, for similar applications. This offers benefits in terms of total cost, material consumption, and environmental impact. The paste formulation showcases a complex non-Newtonian behavior, where yielding flow and thixotropicity are found to be independent and dependent on preshear conditions, respectively. This behavior can be attributed to the network orientation and rearrangement of filler structures within the paste system, which in turn are responsible for filler pattern uniformity and overall printing quality. Compared to traditional conductive materials, HRCM pastes are proven to be a viable alternative for RF devices fabrication, including printed Wi-Fi antennas.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"38 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141781997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These hydrogels combine the intrinsic properties of proteins with the resilience of synthetic polymers, offering a versatile application platform. Central to our research is the trypsin-induced simultaneous functionality of controlled drug model release and dynamic shape changes under physiological trypsin concentrations (0.01% w/v). These hydrogels display tailored mechanical and physical properties and microstructure, which are crucial for biomedical devices, soft robotics, and tissue engineering applications. Additionally, the hydrogels effectively control the release of fluorescein isothiocyanate, a model drug, indicating their potential for highly targeted drug delivery, particularly in the gastrointestinal tract.

Currently, the topical application of antimicrobials restricts the delivery of drugs to the critical areas of the wound bed, largely due to barriers posed by the necrotic tissue, scab formation, and bacterial biofilms, which severely diminish the bioavailability of the therapeutics. MNs have enabled efficient and targeted delivery to overcome many chronic wound challenges. Over the past decade, significant progress has been made to develop MNs with unique properties tailored for the delivery of vaccines, anticancer, and antimicrobials. As ongoing research continues to refine MN design, material properties, and drug formulations, the potential for revolutionizing antimicrobial drug delivery for efficacy, patient experience, and therapeutic outcomes remains at the forefront of scientific research. In this review, insights are provided into the latest progress, current developments, and the diverse applications of MNs for antimicrobial drug delivery.

DC-mediated immune surveillance requires morphology changes to adapt to the physical and biochemical cues of the external environment. These changes are assisted by a dynamic actin cytoskeleton–membrane interface connected to surface receptors that will trigger signaling cascades. In recent years, the development of synthetic immune environments has allowed to investigate the impact of the external environment in the immune cell response. In this direction, the bioengineering of functional topographical features should make it possible to establish how membrane morphology modulates specific cellular functions in DCs. Herein, the engineering of one-dimensional nanostructured SiO2 surfaces by soft-nanoimprint lithography to manipulate the membrane morphology of ex vivo human DCs is reported. Super-resolution microscopy and live-cell imaging studies show that vertical pillar topographies promote the patterning and stabilization of adhesive actin-enriched structures in DCs. Furthermore, vertical topographies stimulate the spatial organization of innate immune receptors and regulate the Syk- and ERK-mediated signaling pathways across the cell membrane. In conclusion, engineered SiO<sub>2</sub> surface topographies can modulate the cellular response of ex vivo human immune cells by imposing local plasma membrane nano-deformations.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"3 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141754106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
