Efficient single-cell isolation technology can significantly enhance low-abundance single-cell detection sensitivity. However, the lack of individual control over each target cell hinders further bio-analysis. Here, a “cell-on-demand” large-scale digital microfluidics platform is reported for real-time low-abundance single-cell manipulations. Compared to the conventional strategy that sequentially identifies the target cells among the heterogeneous population, the “cell-on-demand” method can conduct targeted-search-guided target cell isolation, enabled by on-demand droplet splitting. The results demonstrate that “cell-on-demand” is nearly eightfold more effective compared to the conventional strategy in dealing with low-abundance (1%) single-cells. To validate the system's feasibility, heterogenous tumor spheroids samples are used for isolating homogeneous single-target tumor spheroids, in integration with subsequent drug sensitivity testing and analysis. Drug sensitivity results show significant differences in half-maximal inhibitory concentration (IC50) for three chemotherapy drugs: Fluorouracil, Irinotecan, and Oxaliplatin, while in high consistency with well-plate-based assays. With the capability of processing both high and low-abundance samples, the proposed platform shows potential in handling various samples and in broader applications.","PeriodicalId":228,"journal":{"name":"Small","volume":"4 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211713","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}

This study explored doping alginate hydrogels with micro–nanomaterials to improve their electro–mechano–chemical performance. Carboxylated multi–walled carbon nanotubes are covalently bonded to sodium alginate (SA) through esterification, enhancing electrical conductivity and response actuation. Graphene oxide formed a compact structure via carboxyl and hydroxyl interactions, dispersing SA molecules, reducing agglomeration, and enhancing ion channel stability, which reduced resistance by 36.8%. Meanwhile, the sulfonic acid group in polystyrene sulfonate sodium improved water retention and lowered the elastic modulus. Crosslinking with SA created a stable hydrogel network, boosting anion concentration and aiding hydrated cation migration. This led to a 52.3% decrease in the elastic modulus of AHAM, resulting in a maximum actuated force–mass ratio up to 5.9 times higher than the control group.","PeriodicalId":228,"journal":{"name":"Small","volume":"16 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211286","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}

However, there are nearly no reports on the low-temperature deposition of metal sulfide thin film. In this study, leveraging the flexibility in precursor selection afforded by mist chemical vapor deposition, a solution-based combustion-assisted film deposition technique is employed to achieve the low-temperature deposition of Bi2S3 thin films. The Bi(NO3)3 and thiourea & hydrazine hydrate are applied as the oxidizer and fuel, respectively. The deposition mechanism is discussed from the temperatures and the concentration of additives (hydrazine hydrate and NaOH). The photoelectrochemical photodetectors fabricated using the solution-processed Bi2S3 thin films demonstrated interesting photodetection performance, exhibiting remarkable responsivity, rapid response speed, and high stability over 3600 s.

The resulting PS-grafted SiO2 particles exhibit exceptional colloidal stability and compatibility with conventional hydrophobic NCs, enabling their ordered coassembly into hybrid binary superlattices with unprecedented structural diversity. In particular, hidden subsurface NCs are revealed at interstitial voids in multiple binary phases, highlighting structural complexities beyond those of conventional binary colloidal crystals. Furthermore, selective etching of SiO2 colloids produces non-close-packed NC superlattices that are challenging to achieve through direct assembly.

In this study, molecular dynamics (MD) simulations are employed to systematically investigate the complete Li-ion transport progress, encompassing the electrolyte, organic/inorganic SEI components, and two critical interfaces: electrolyte/organic SEI and organic SEI/inorganic SEI. The results indicate that Li ions in the organic SEI retain either full or partial solvation shells. Free energy profiles reveal that the highest energy barrier emerges at the organic–inorganic SEI interface due to the complete desolvation of Li ions and structural differences between the organic and inorganic SEI layers. By constructing a comprehensive free energy landscape for Li-ion transport, this study offers valuable insights into the relationship between SEI composition, structure, and interfacial dynamics.","PeriodicalId":228,"journal":{"name":"Small","volume":"08 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211645","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}

However, there are other less studied factors such as solubility and diffusion of reactants in the reaction system, which are also responsible for sluggish kinetics and can alter the reaction selectivity. The conventional diphase photocatalytic reactions at the liquid–solid interface suffer from poor solubility and slow transport of the reactants in a reaction medium. The emerging triphase photocatalysis, which occurs at the gas–liquid-solid interface and liquid–liquid–solid interface has shown the potential of addressing these less-studied issues and achieved better performance than the diphase photocatalytic reactions. This review article mainly focuses on the understanding of the mechanism and basic difference between diphase and triphase photocatalysis along with the requirements for triphase photocatalysis. Several examples of triphase photocatalytic reactions including CO2 reduction, N2 fixation, H2O2 production, and organic pollutant degradation are discussed in detail in this review.

The lower hydrogel carries microrobots of Chlamydomonas rheinhardtii (C. rheinhardtii), which continuously release bio-oxygen under light irradiation to alleviate hypoxia in deep wound tissues. The upper layer carries Ag─FA NPs formed by Ag+ and FA self-assembly chelation complex, which can effectively inhibit bacterial growth and remove bacterial biofilms through photothermal-therapy-based Near - Infrared (NIR) 808 nm. C. reinhardtii and Ag─FA NPs synergistically scavenge excessive ROS. Therefore, a new concept of “three-pronged strategies” that addresses multiple problems in the wound microenvironment of diabetic patients has been proposed.

Herein, a method for post-treating perovskite films in p-MPSCs at room-temperature using halogen-free aromatic amines, including Benzylamine (BA), 1-Naphthalenemethylamine (NMA), and 1-Naphthalenecarboximidamide (NFA), is reported. The halogen-free aromatic amines prevent the formation of iodine vacancy defects in perovskite films by interacting with under-coordinated Pb2+, significantly reducing the trap state density of the perovskite films. Meanwhile, the halogen-free aromatic amines can form low-dimensional perovskites with type II energy level alignment at the perovskite film/carbon electrode interface, which significantly suppresses non-radiative recombination of interfacial carriers and reduces VOC loss. As a result, the champion power conversion efficiency (PCE) of p-MPSCs based on NFA room-temperature post-treatment is improved from 17.51% in control devices to 20.27%, and the VOC is increased from 0.975 V in control devices to 1.049 V. Furthermore, the unencapsulated p-MPSCs retained more than 95% of their initial PCE after being stored in air for 3500 h.
