However, salt ion accumulation and crystallization persist during long-term operation, which remains a key challenge. In this work, we report a hydrophilic–hydrophobic Janus nanofiber membrane evaporator, which is prepared <em>via</em> continuous microfluidic electrospinning. This method allows <em>in situ</em> chemical reaction of tannin (TA) and Fe<small>³⁺</small> to be carried out in a “Y” chip during the spinning process, enabling rapid, facile, and flexible fabrication of the nanofiber membrane. TA is rich in hydroxyl groups, which endows the bottom layer with hydrophilicity and electronegativity, thereby enhancing the water transport and Donnan effect. Thus, a high evaporation rate of 1.73 kg m<small>⁻²</small> h<small>⁻¹</small> in pure water is achieved. More importantly, long-term stability in seawater desalination is realized with an evaporation rate of 1.68 kg m<small>⁻²</small> h<small>⁻¹</small>, and there is no salt crystallization on the surface during continuous evaporation for 8 hours in 10 wt% NaCl solution. On the one hand, the bottom layer shows electronegativity, which is liable to immobilize cations Na<small>⁺</small> and repel anions Cl<small>⁻</small>, achieving the purpose of salt resistance. On the other hand, the Janus structure also favors the redissolution of concentrated salts into raw water, further avoiding salt accumulation. This work offers a promising common strategy for constructing high-performance Janus evaporator, which will stimulate the development of seawater desalination.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" 8","pages":" 1741-1748"},"PeriodicalIF":8.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we have used AF3 to model a list of commonly used DNA nanomotifs and compared the AF3 structures with the experimentally observed structures reported in the literature. For asymmetric motifs, AF3 structures are consistent with the experimental observations; but for symmetric motifs, AF3 structures are often substantially different from experimental observations. However, the fails can be rescued if the symmetric motifs are converted into corresponding asymmetric motifs by breaking DNA sequence symmetry while maintaining the backbone symmetry. This study suggests that while AF3 is immensely helpful, we as experimentalists should use it (as it currently stands) with caution. In addition, AF3 needs further development to incorporate the existing experimental data in the training dataset for AF3.

Nonetheless, their inherent biomolecular limitations pose significant challenges, including cost and storage constraints. We propose an alternative conjugation for antibodies based on catalytic bimetallic nanoclusters and their integration in such simple colorimetric paper-based immunoassay. The nanoclusters are composed of gold and platinum and they are embedded in the structure of an anti-rabbit antibody, integrating in a single component the biorecognition and transduction elements required for biosensing. The detection is based on the catalytic properties of the NCs to oxidize an insoluble chromogenic substrate, generating a visible signal on the surface of the paper that can be further analysed for quantitative results. We demonstrate the detection of antibodies against the inflammation biomarker interleukin-6 with a limit of detection of 200 ng mL<small>⁻¹</small>. Experimental results reveal improvements in terms of stability compared to the natural enzyme horseradish peroxidase, retaining most of its activity after a storage equivalent to 6 months at 4 °C.

This study investigated the development of pirarubicin and gemcitabine co-loaded polymeric nanoparticles for synergistic activity against breast cancer cells. To enable sustained and site-specific delivery within the tumor microenvironment, both pirarubicin and gemcitabine were chemically conjugated to a polylactic acid-based block copolymer <em>via</em> a pH-responsive “Schiff's base” linkage. The synthesized polymer–drug conjugates were subsequently formulated into Pira–Gem co-loaded block copolymeric nanoparticles, demonstrating good stability and minimal toxicity towards non-cancerous cells.

Furthermore, they showed superior cellular uptake on 2D adherent cancer cell lines relative to free drugs in <em>in vitro</em> studies. Both apoptotic analysis and cell proliferation inhibition studies revealed that the co-loaded nanoparticles exhibited a synergistic therapeutic effect across multiple breast cancer cell lines, surpassing the efficacy of Pira/Gem single drug-loaded nanoparticles and their free drug counterparts.
