Here, a self-mineralized bioorthogonal probiotic platform with the expression of anti-PD-L1 nanobodies was developed for cancer chemoimmunotherapy. This platform selectively accumulated and deeply penetrated into tumor tissues, where the palladium-mineralized probiotics catalyzed bioorthogonal bond-cleavage to generate chemotherapeutic drugs and induced immunogenic cell death. Under laser irradiation, the indocyanine green modified probiotics were ruptured and released nanobodies which effectively suppressed tumor immune evasion and ultimately led to the tumor-specific immune responses.

Such phenomena are more often encountered at nanoscale and have been utilized to build nano-devices such as nanowire-based interconnects or electrodes. Clearly, cold welding could be merely driven by the elastic adhesive contact, the analysis of which is straightforward but does not involve a time dependence. Room temperature, nanoscale, and contact size growth might suggest the operation of the curvature-driven sintering mechanism, or result from our proposed interfacial diffusional process in this paper as driven by a stress gradient (i.e., Coble creep). Here, we fabricated silver nanowires (AgNWs) with radius of several tens of nanometers, placed them into interconnect-like contacts, and measured the contact size growth at selected temperatures up to 200 °C. Out of the two hypothetical mechanisms (sintering versus Coble), only the latter mechanism can compare favorably with our experiments and result into physically meaningful parameters such as the activation energy and stress gradient magnitude. Consequently, this work presents the first conclusive study for nanoscale cold welding, as being the Coble diffusional creep.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"80 ","pages":"Pages 905-912"},"PeriodicalIF":21.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142720919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 provide a detailed computational-experimental characterisation of the archetypal NFA, Y6. To explain the significant broadening and red shift of the absorption spectrum observed when moving from the solution phase to the solid state, we first rule out more typical causes, such as J-aggregation. Instead, by considering the role of charge transfer (CT) excitations and their mixing with Frenkel exciton (FE) states, we can computationally reproduce the experimental absorption spectra of Y6 with excellent accuracy. Using transient absorption spectroscopy, we provide evidence for this dense manifold of FE-CT hybrid electronic excitations in Y6 through the prominent sub-picosecond relaxation events following supra band gap excitation. Furthermore, through sub band gap excitation, we also find states with polaronic character in Y6 that are in a dynamic equilibrium with the FE-CT hybrid states. Magnetic resonance spectroscopies reveal that these polaronic states are polaron pairs, most likely located on neighbouring Y6 molecules, not free charge carriers, as has been previously suggested. Thus, this new understanding of how the solid-state packing motif directly controls the optical and electronic properties of Y-series NFAs opens the door to intelligently design NFA materials to further increase OPV performance.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"80 ","pages":"Pages 308-326"},"PeriodicalIF":21.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142721083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this challenge, we present a method for embedded printing in non-yield stress fluids using sequential printing in a reversible ink template (SPIRIT) strategy. By leveraging an omnidirectional elastic constraint provided by conventional supporting baths, we can precisely fabricate GelMA and HAMA hydrogels into functional tissue constructs with both intricate external structures and internal vessel systems, which cannot be achieved with extant embedded printing techniques. As a proof of concept, we successfully printed a complex ventricle model with high cell density and internal channels using GelMA hydrogel, which demonstrated high cell viability and synchronous beating performance.

The assay, which does not require DNA amplification, demonstrated the ability to detect these pathogens with a detection limit of 7–8 copies/µL and achieved a clinical sensitivity of 100 % in detecting Chlamydia trachomatis and Neisseria gonorrhoeae from 60 de-identified clinical samples. Additionally, it directly detects DNA from these pathogens without the need for DNA extraction, employing a multiplexed lateral flow-based platform suitable for rapid clinical monitoring.
