A comprehensive understanding of nanoscale strain evolution involved in these processes can advance our knowledge of underlying mechanisms and facilitate material design improvements. However, traditional microscopy workflows face challenges due to trade-offs between field of view (FOV), spatial resolution, temporal resolution, and electron beam damage, particularly in gas or liquid environments. Here, we demonstrate <em>in situ</em> nanometer-resolution strain and orientation mapping in a temperature-controlled gas environment with a large FOV. This is achieved by integrating a microelectromechanical system (MEMS)-based closed-cell TEM holder, precession-assisted four-dimensional scanning transmission electron microscopy (4D-STEM), and a direct electron detector (DED). Using the strain evolution during zirconium initial oxidation as a case study, we first outline critical strategies for focused ion beam (FIB) gas-cell sample preparation and gas-phase TEM workflows to enhance experimental success. We then show that integrating DED with precession electron diffraction (PED) and optimizing gas pressure substantially improve the quantity and quality of the detected Bragg peaks in nano-beam electron diffraction (NBED) patterns, enabling more precise strain and orientation measurements. Furthermore, we introduce a practical protocol to pause the reactions, allowing sufficient time for 4D-STEM data collection while ensuring the temporal resolution needed to resolve material dynamics. Our methodology and workflow provide a robust framework for quantitative analysis of chemomechanical evolutions in materials exposed to gas or liquid environments, paving the way for improved material design in energy-related applications.</div></div>","PeriodicalId":395,"journal":{"name":"Nano Today","volume":"64 ","pages":"Article 102784"},"PeriodicalIF":13.2,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071766","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 study, we have developed a multistage nanotherapeutic (DHA-lys@miRNA) to address both anti-infection and secondary scarring hyperplasia during the treatment of bacterial keratitis. Specifically, docosahexaenoic acid (DHA) and ε-polylysine (ε-PL) were successfully self-assembled to form an amphipathic cationic nanocarrier, DHA-lys, which can complex with microRNA to form nanotherapeutics. This nanosystem exhibits potent bacteriostatic effects and amphiphilicity, enabling it to bind to the tear film lipid layer and conjunctival mucosal layer, thereby significantly enhancing its residence time and penetration in the corneal tissue. This, in turn, improves the bioavailability of the drug in bacterial keratitis. Furthermore, we have identified miR-361–3p as a key microRNA through database screening and a series of experiments. This microRNA can specifically inhibit corneal fibrosis by interrupting the crosstalk between corneal stromal cells and myofibroblasts in a BK mouse model <em>in vivo</em>.

Therefore, the need to develop new and efficient prevention and treatment strategies is urgent. Here, we successfully developed a noninvasive drug delivery system involving a ferritin (Fn)-based drug delivery platform. To further increase therapeutic efficacy, we loaded cimifugin (Ci), an active ingredient extracted from <em>Cimicifuga racemosa</em>, into Fn to form the complex Ci@Fn. Ci@Fn was injected through the retroauricular round window membrane and then transported to the basement membrane along with the flow of ectolymphatic and endolymphatic fluids. Further through the targeting function of Fn, Ci@Fn was able to precisely target hair cells (HCs). Subsequently, Ci@Fn is endocytosed by HCs and releases Ci in lysosomes, exerting its protective effect on HCs. Neonatal mouse model experiments revealed that Ci@Fn significantly reduced cisplatin (Cis)-induced cochlear hair cell damage and prevented hair cell loss and apoptosis. In addition, RNA sequencing analysis revealed that Ci@Fn attenuates Cis-induced ototoxicity mainly by modulating the PI3K-Akt signaling pathway. Finally, in validation experiments in an adult mouse model of noise-induced hearing damage, we found that Ci@Fn had a significant hearing-protective effect, superior to the current gold standard treatment (dexamethasone). These findings demonstrate that Ci@Fn is an innovative and efficient solution for hearing loss treatment and lays a solid foundation for future clinical applications.</div></div>","PeriodicalId":395,"journal":{"name":"Nano Today","volume":"64 ","pages":"Article 102790"},"PeriodicalIF":13.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941308","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}

The synthesized nanoplatform (PDA/ICG/CpG, PIC) was integrated with polydopamine (as a photosensitizer), indocyanine green (as the imaging probe), and CpG ODN (as the immune adjuvant) for fluorescence imaging-guided photothermal-immunotherapy.

The tumor microenvironment, which has severely hindered drug delivery in recent research, may facilitate transportation via ISI. Under laser irradiation, tumor cells were killed by hyperthermia, whereby tumor-related antigens were released to promote the maturation of dendritic cells (DCs), evoking T lymphocyte activation. Aided by CpG, DC maturation, and CD8⁺ T-cell infiltration into the tumor, draining lymph nodes and spleen were significantly amplified.

To mitigate this adverse effect, a nanozyme-loaded nanofiber dressing, termed GIPH, was developed.
