In addition, airborne microorganisms can spread dangerous diseases, compounding the issue. A widely used method for mitigating the risks of airborne particles is air filtration. While effective at particle removal, conventional air filters typically lack additional functionalities. They cannot inactivate accumulated contaminants, and they require periodic replacement to remain safe. This work presents a multifunctional, self-cleaning air-filtration system using a graphene-enhanced air filter medium (GeFM). The GeFM is capable of capturing >95% of microorganisms and particles >1 μm and can be repeatedly joule heated to >300°C, regenerating the filter. Furthermore, the GeFM provides unique options for monitoring the airflow and loading status of the filter. The GeFM can improve filter lifetime and safety, offering great potential for the development of advanced and likely more sustainable air-filtration solutions in the future.","PeriodicalId":101324,"journal":{"name":"Device","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136117411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, recent studies have shown that devices capable of capturing/directing electromagnetic waves can artificially focus incident light into sub-wavelength active areas, thus enabling applications such as photodetection and communication in defiance of the diffraction limit. Despite these advancements, the ultimate scaling limits of photodetectors have remained largely untested. Here, we present a two-dimensional (2D) monolayer molybdenum disulfide phototransistor that can reach specific detectivities greater than 1013 Jones and display a high dynamic range while possessing an electrical active area of only 0.0065 μm2. Together, the nanoscale active area and ultra-thin-body nature of the sensing material correspond to an active volume of ∼4.23 × 10−6 μm3. These results indicate that scaling of 2D photodetectors beyond the diffraction limit has enormous potential so long as methods of focusing incident light continue to be developed/refined concurrently.","PeriodicalId":101324,"journal":{"name":"Device","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136009167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current patterning methods for these materials have low process compatibility and are generally laborious and time-consuming, making it challenging to use them for various types of devices. Here, we demonstrate a conformable microneedle sensor applied using a photopatternable gel electrolyte and skin adhesive for glucose monitoring. We used oxygen inhibition photolithography to pattern the gel electrolyte and modified a thermocurable adhesive for positive photolithography, enabling precise and direct deposition onto a microneedle substrate. The resulting microneedle sensor establishes a stable electrical and physical interface with skin and is highly sensitive over a broad range of glucose concentrations. We tested the microneedle sensor for diagnosing hyperglycemia in an anesthetized rat through stable, continuous glucose monitoring.","PeriodicalId":101324,"journal":{"name":"Device","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135963869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides material innovations, researchers have explored different design strategies for these AWH devices, which can be divided into monocyclic and multicyclic types. Monocyclic water harvesters can be further categorized into those using upward vapor escape, for which research efforts have focused on reducing top cover heating and increasing sorption capacity, and those using downward vapor escape, for which research efforts have focused on heat recycling and cooling strategies to enhance condensation efficiency. Notably, some of these devices utilize radiative cooling and require zero external energy input. For multicyclic water harvesters, efforts have focused on optimizing the sorbents’ water uptake kinetics and device design geometry to guarantee continuous water harvesting.","PeriodicalId":101324,"journal":{"name":"Device","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135963066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PyLabRobot provides an interface for a universal set of commands and deck layout representations while enabling the control of diverse accessory devices. The interface can work with any liquid-handling robot capable of aspirating and dispensing precise volumes of liquid within a Cartesian coordinate system. In addition to the already integrated robots, we include guidance on integrating new liquid-handling systems and accessories. We validated the framework through unit tests and application demonstrations, including a browser-based simulator, a position calibration tool, and a path-teaching tool for complex movements.
