Evaporating the metal in ultra-high vacuum (10⁻⁹ Torr) is a recognized method to reduce the damage, but the higher complexity and cost of the setup and its lower throughput makes developing other solutions highly desirable. All studies on ultra-high vacuum evaporation of metals on 2D materials evaluated the figures-of-merit of transistors fabricated following different protocols, with very scarce or without sub-nanometre information. Moreover, such studies employed 2D materials produced by chemical vapour deposition (CVD), which contain relatively large amounts of native defects, and hence, post-evaporation analyses do not allow identifying which defects are native and which ones are generated during metal evaporation. In this article we analyse the structure of defect-free mechanically exfoliated 2D materials via cross-sectional transmission electron microscopy (TEM) before and after Au evaporation (on top), and calculate the density of defects introduced. We find that evaporating the metal in a moderate vacuum atmosphere of 5 × 10⁻⁶ Torr is sufficient to avoid damage, leading to a nearly perfect van der Waals interface. By using density functional theory simulations we find that the presence of water molecules on the surface of the 2D material slightly distorts the position of the atoms in the crystalline hexagonal network, weakening the covalent bonds and reducing the energy for defect formation. We fabricate Au/h-BN/Au devices and observe that evaporating the Au at 5 × 10⁻⁶ Torr produces much less out-of-plane leakage current than evaporating at 3 × 10⁻⁵ Torr. The approaches here presented are easy to use and facilitate the introduction of 2D materials in electronic devices and circuits.</p></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"160 ","pages":"Article 100831"},"PeriodicalIF":31.6,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141953997","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}

Despite their efficacy, triterpenoid chemotherapeutics face significant challenges in cancer therapy because of their poor aqueous solubility, which restricts the utilization of potent drug variants. Consequently, there is a pressing need to develop a solubilized form of triterpenoid encapsulated within mechanically robust biomaterials, to facilitate injectable and minimally invasive delivery. In this study, we focused on ginsenoside compound K (CK), a natural pentacyclic triterpenoid. It was conjugated to hyaluronic acid (HA-CK) and employed as a novel guest molecule for binding to β-cyclodextrin-grafted hyaluronic acid (HA-βCD), which is the host polymer. This interaction resulted in the creation of an injectable supramolecular hydrogel (HG-Gel) through a straightforward mixing process involving host–guest interactions between βCD and CK. The physical properties of the hydrogels were easily manipulated by altering the molecular weight of HA and the grafting degree of βCD and CK in HA. Notably, the supramolecular hydrogel precursors exhibited excellent cell viability for normal cells, sparing over 80 % of NIH 3T3 and HaCaT cells. Intriguingly, these hydrogels facilitated effective delivery to CD44-overexpressing cancer cells, suppressing cell proliferation. Enhanced trafficking of CK to cancer cells heightened caspase-dependent apoptosis in B16F10 cells, with the extent of cell death contingent on the expression levels of CD44 in cancer cells. This effect of CK seems to be mediated through the induction of intracellular reactive oxygen species (ROS) and mitochondrial membrane potential loss. In melanoma tumor-bearing mouse models, HG-Gels effectively inhibited tumor growth. Importantly, no side effects were observed on normal tissues, underscoring the safety of naturally derived biomaterials. This study underscores the superiority of HG-Gels as a platform for utilizing triterpenoid saponins in melanoma therapy, suggesting their potential for enhancing the safety and efficacy of triterpenoids in cancer treatment.</p></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"160 ","pages":"Article 100824"},"PeriodicalIF":31.6,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0927796X24000548/pdfft?md5=698faa6a020309359c8471ccb23223ae&pid=1-s2.0-S0927796X24000548-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141636926","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}
