Here, we present the use of ultrathin pyrolyzed polymer films (PPFs) as the gate electrode, enabling the fabrication of highly efficient planar hot electron emitters (PHEEs). The thickness of the PPF was observed to be roughly 1 nm across a full 4” wafer, approaching the monolayer limit. Conductivities of up to 3.5 × 10<sup>4</sup> S/m at pyrolysis temperatures of only 900 °C were measured, representing a 2-fold increase compared to bulk values. This renders an easily accessible 2D material with high electron transparency. Thus, the PHEE exhibits very high transfer ratios of up to 31% and proves to be stable at high pressures over an extended period of time. Furthermore, the straightforward integration route of the PPF presented here comprises only two steps: photolithography and subsequent pyrolysis. The fabricated devices exhibit high uniformity in performance, with a transfer ratio standard deviation of 2.9% across a single wafer. Ultimately, the devices were fabricated exclusively with silicon dioxide on silicon in combination with carbon, which represents a sustainable fabrication approach with inert materials. It has been demonstrated that the PHEE can also operate in both nitrogen and air, illustrating the utility of these emitters for gas ionization and sensing.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"11 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184089","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, the nondegradable nature and complex functionalization process of traditional dry electrodes limit their widespread use. In contrast, mycelium-based biovegan leather offers an ideal alternative for flexible electrodes, providing benefits such as biodegradability and ease of preparation. To overcome the mechanical performance and stability challenges inherent in pure mycelium, this study develops a mycelium–polypyrrole composite material (P-MCM) that demonstrates reliable mechanical and electrical properties, making it suitable for the daily monitoring of human electrophysiological signals. The P-MCM exhibits a tensile strength of 3 MPa, an elongation at break of 13%, a conductivity of 51.10 S/m, and an interface impedance of 52.6 kΩ/cm<sup>2</sup> for the electrode–skin system at 10 Hz. The low interface impedance of P-MCM electrodes allows for the stable acquisition of electrocardiogram, electromyogram, and electroencephalogram signals with performance on par with commercial electrodes. It is expected that this work will provide valuable insights and foundational materials for the advancement of flexible electrodes.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"12 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184068","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}

Moreover, PDT alone often fails to fully inhibit tumor growth, prompting its combination with other modalities such as photothermal therapy (PTT), which induces tumor cell death through localized heating. In this study, we developed a nano-bacteria biohybrid, EcN-QS-iLux@Pd@MC540, by biomineralizing the engineered probiotic <i>Escherichia coli</i> Nissle 1917 (EcN-QS-iLux) with palladium nanoparticles and loading it with the photosensitizer MC540. This biohybrid performs self-driven PDT without external light and effective PTT under 808 nm light excitation. In vivo studies using a 4T1 tumor mouse model demonstrated complete tumor inhibition through the synergistic action of PDT and PTT, with no significant systemic toxicity.

By leveraging the computational efficiency and generalization capabilities of deep learning alongside the robustness of classical optimization, hybrid frameworks enable faster convergence, higher design efficiency, and the exploration of diverse, fabrication-feasible solutions. Additionally, methods such as a physics-informed neural network are also discussed for their significant role by embedding governing physical laws into the learning process to reduce data dependency and enhance interpretability.

Their large-scale commercialization hinges on the design and development of cost-effective, stable electrode materials with high surface area and exceptional conductivity.
