These defects are only a few hundred micrometers, and the corresponding distorted electric fields are extremely weak. Consequently, it is challengeable for existing sensing methods to detect these defects and distorted electric fields accurately, in situ, and nondestructively under electrically charged conditions. Inspired by the warning bioluminescence of ctenophores, we designed a field-coupling microsphere (FCM) with high sensitivity of microscopic defects and distorted electric fields. When the FCM is located in a distorted electric field, the micron-scale luminescent units on its surface precisely sense this distorted electric field and emit in situ electroluminescence, thus exposing defects and distorted electric fields. Furthermore, we prepared a recyclable electrosensitive coating (REC) by compounding FCMs into phase-change matrix materials that are applicable to the surfaces of electrical and electronic equipment to accurately sense microscopic defects and distorted electric fields. To the best of our knowledge, this is the first smart coating material to visualize invisible distorted electric fields using field-coupled electroluminescence, which provides a novel method to study electric field evolution inside dielectrics and to detect microscopic defects in electrical and electronic equipment.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"68 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701013","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, traditional strain sensors often face challenges in achieving both high sensitivity and wide detection range simultaneously, typically sacrificing one characteristic to enhance the other. Here, we present a novel design of strain sensors featuring a dual-gradient crack structure by film thickness modulations. The first gradient (local scale) facilitates the gradual crack opening in the film during the stretching process, enabling precise mechanical response. The second gradient (global scale) modulates the degree of the local gradients across the entire surface, where small local gradients ensure sensitivity and large local gradients extend the working range. Phase field simulations confirm the stable and controlled crack propagation modulated by film thickness gradients, aligning with the experimental results. The dual-gradient crack strain sensor exhibits ultrahigh sensitivity (∼9 × 106) and wide detectable strain range (∼80%). Moreover, the sensor features a low detection limit (0.02%), short response time (∼60 ms), and excellent durability over 22,000 test cycles. The dual-gradient crack sensor excels in detecting human motions, from subtle facial expressions to large joint movements, highlighting its promising potential for applications in flexible electronics and health monitoring systems.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"144 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701014","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, their practical applications are hindered by a relatively low efficiency and poor stability. The establishment of a buried interface architecture can effectively enhance the long-term stability of the C-PSC devices. Nevertheless, defect generation during perovskite formation and associated nonradiative carrier recombination remain challenges. Herein, we introduce a bidirectional coordination strategy utilizing ammonium acetate (CH3COONH4) to passivate the tin dioxide (SnO2) surface. The CH3COONH4 treatment facilitates SnO2 oxygen vacancy passivation via interactions between CH3COO- groups and Sn4+ cations. Simultaneously, perovskite defects are effectively mitigated by the combination of CH3COO- with uncoordinated Pb2+ and the formation of N-H···I- hydrogen bonds. These interactions provide a promising foundation for perovskite crystal growth and promote vertical crystallization. Additionally, a favorable buried interface between the perovskite and underlying SnO2 layer effectively minimizes nonradiative recombination losses. Benefiting from these merits, C-PSC devices with CH3COONH4-passivated SnO2 achieved a maximum PCE of 15.5% and demonstrated exceptional operational stability, exceeding 1000 h under ambient conditions. This synergistic bidirectional coordination strategy provides an effective route for fabricating efficient and durable C-PSC devices.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"4 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693537","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 proposes a multipathway and highly efficient treatment strategy for melanin deposition. A microneedle (MN) system based on hydrolyzed collagen (HC) and polyvinylpyrrolidone (PVP) was designed to precisely deliver Chlamydomonas reinhardtii (C. reinhardtii) and potassium 4-MSK (C.r&4-MSK-MN) to skin tissues. C. reinhardtii contains unique antioxidant components such as arsenoproteins, polyunsaturated fatty acids (PUFAs), and algal polysaccharides, which distinguish it from other microalgae like Chlorella. In vitro free radical scavenging experiments show that at a concentration of 1 × 109 cells/mL, C. reinhardtii exhibits scavenging rates of 89.26%, 101.44%, and 103.57% against DPPH·, ABTS·+, and ·OH radicals, respectively. In addition, potassium 4-methoxysalicylate (4-MSK) can inhibit tyrosinase activity and promote skin metabolism. Therefore, C.r&4-MSK-MN has the following advantages: on one hand, C.r&4-MSK-MN successfully breaks through the skin barrier, directly delivering C. reinhardtii cells to the target site to scavenge free radicals and reduce the stimuli for melanin production. On the other hand, 4-MSK inhibits tyrosinase activity to reduce melanin synthesis and, at the same time, promotes skin metabolism to reduce melanin deposition on the skin surface, achieving multipathway reduction of melanin deposition. Experimental results showed that in animal models, C.r&4-MSK-MN significantly reduces the epidermal thickness of rats and substantially decreases melanin production. This research outcome not only provides a new strategy for the treatment of melanin deposition but also confirms that microalgae have potential application prospects in the fields of skin care (such as whitening and antiaging) and cosmeceuticals.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"115 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701007","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}

Fluorescence probes exhibiting aggregation-induced emission (AIE) characteristics stand out as exceptional candidates for imaging due to their photostabilities and sensitivities. However, the hydrophobicity of the AIE functional groups limits their broad applicability. To overcome this limitation, we employed AIE by incorporating tetraphenylethylene (TPE) groups into amphiphilic blocks and random copolymers with varying lengths of 2-(dimethylamino)ethyl methacrylate (DMAEMA) segments. These new polymers demonstrate self-assembly behaviors forming fluorescent, core-shell micelles in aqueous environments and can serve as dual-functional stabilizers for monoolein-based lipid nanoparticles (MO-based LNPs) containing intricate inverse cubic (Q2) and hexagonal (H2) mesophases. Through rational design of incorporating DMAEMA, a pH-dependent enhancement in TPE fluorescent intensity for both nanosystems, the self-assembled polymer micelles and polymer-stabilized LNPs, was achieved. Successful fluorescence imaging of the novel polymer-stabilized LNPs was demonstrated in HeLa cells by confocal microscopy. This study represents the first instance of utilizing TPE- and DMAEMA-based block copolymers as fluorescent stabilizers for LNPs, with tunable fluorescent intensities by variations of DMAEMA block length and environmental pH. These findings underscore the significance of AIE block copolymers with tunable physicochemical properties for fluorescence imaging of nanomaterials in biological systems.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"27 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693531","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}
