Fabrication of nanoparticle-LIG composites increases the functionality of the material and enhances catalytic or antibacterial activities of related surfaces; however, less is known for nanoparticle-LIG composites that modulate fouling. Here, we show SiO2-doped LIG by lasing polyethersulfone-diatomaceous earth membrane composites, which resulted in superhydrophilic surfaces with enhanced anti-adhesion and anti-bio-adhesion performance. The diatomaceous earth converted to crystalline SiO2 that is uniformly coated on the LIG surface during the laser treatment. Increased surface oxygen-containing functional groups are also observed, which enhanced the hydrophilicity of the LIG composite. Anti-adhesion properties of the hydrophilic SiO2-LIG are exemplified by a reduced binding of methylene blue and Pseudomonas aeruginosa, representing an organic pollutant and bacterial adhesion, respectively. The variable surface properties of silica nanocomposite surfaces might be useful in water treatment membranes, but silica-doped LIG might also lead to uses in other applications, such as sensing or semiconductors, if the electronic properties of the material can be altered.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500683","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146007413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, improving the functionality of SIS meshes remains a huge challenge. Herein, a multifunctional SIS mesh is designed by modifying it with protocatechualdehyde (PCA), a polyphenolic molecule, combining with magnesium ion (Mg2+) for full-thickness abdominal wall defect repair in a rat model. The prepared SIS/PCA/Mg meshes exhibit significantly prolonged degradation cycle, excellent biocompatibility, and antioxidant property and effectively promote the M2 polarization of macrophages. In addition, this mesh can remarkably inhibit the growth of bacteria, which is beneficial for preventing postoperative infections. More importantly, in vivo experiments also confirm that the SIS/PCA/Mg mesh can significantly enhance the repair of full-thickness abdominal wall defects in rats by reducing inflammation, promoting macrophage M2 polarization, and collagen deposition and neovascularization. As a result, the newly developed multifunctional SIS/PCA/Mg mesh shows an attractive prospect for scarless abdominal wall defect reconstruction.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500657","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146007415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, precise isolation of specific cell types with these hydrogels has remained elusive without specific interaction between DNA and cell membrane. Here, a DNA nanostar hydrogel–based method is reported for cell isolation, achieved by interfacing living cells with the hydrogel via an antibody-functionalized DNA motif. As a proof of concept, epithelial cell adhesion molecule (EpCAM)-positive cells are isolated—a model of circulating tumor cells—whose separation from white blood cells is crucial for early cancer diagnosis. By optimizing the antibody-DNA conjugate, a specific binding is achieved between target cells and the DNA gel, enabling the capture of up to 90% of cells. The cells are selectively enriched from a mixture of different cell types using parallelized and iterative capture. The cells recover by dissociating the gel using strand displacement, retain their viability and capacity to proliferate, which supports their future use for culture or analysis. This generalizable method allows coupling of any cell type to DNA gels —supporting future applications ranging from cancer research to recapitulate cellular tumor models in vitro or regenerative medicine to grow designer tissues.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"13 2","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500619","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146007514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These are incorporated into an epoxy-silicone hybrid resin and spray-coated onto various substrates. Compared to traditional rigid alkyl-functionalized CNTs, the LPDMS-coated CNTs show superior water repellency, demonstrated by lower contact angle hysteresis (from 4.9° to 3.1°), reduced roll-off angles (from 7.6° to 3.4°), and enhanced rebound behavior of impacting droplets (reduced contact times and increased number of rebounds). The coatings feature multiscale roughness and maintain superhydrophobicity after abrasion, outperforming surface-textured coatings. The approach is compatible with both hydrophobic and hydrophilic resins, indicating broad applicability. While the anti-icing performance is limited due to a temperature-induced wetting transition, this is effectively addressed by electrothermal (up to 129.4 °C under 100 V) or photothermal (99.92% light absorption) surface heating, restoring the coating's superhydrophobicity.

Here, a strategy is introduced to lower the switching threshold, and the optical sensitivity of the nanoparticle networks (NPNs) is explored.

One network is coated with poly(1,3,5-trivinyl-1,3,5-trimethyl-cyclosiloxane) (pV3D3) using initiated chemical vapor deposition (iCVD), producing Ag/pV3D3 NPN with enhanced morphological stability and a significantly reduced switching threshold of 0.5 V compared to uncoated Ag NPNs (3 V).

The ability of the polymer SDA used herein to self-organize into superstructures while remaining compatible with inorganic building blocks, known as the evaporation-induced self-assembly process (EISA), resulted in a honeycomb-like network of open pores. In contrast to conventional epitaxy, it is demonstrated that the h-LuFeO3 can be readily deposited as polycrystalline thin films on both silicon and quartz substrates by facile dip coating. The formation mechanism of the mesoporous material during calcination in air is investigated using various physicochemical characterization techniques. This revealed that certain reaction intermediates are produced that promote the formation of the hexagonal phase. Density functional theory calculations support the experimentally derived properties and further provide information on the electronic band structure.

We compare two HfO2 with different chemical properties, one grown by thermal ALD (T-HfO2) and the other by plasma-enhanced ALD (P-HfO2), integrated as the gate dielectric on Ta/CoFeB/MgO/AlOx structure. Results show that P-HfO2 exhibits strong frequency dispersion and capacitance enhancement characteristic of redox-active electrochemical capacitors, along with significantly enhanced VCMA, whereas T-HfO2 does not. These findings establish a direct correlation between dielectric C–V behavior and VCMA efficiency.
