Numerous analytical techniques, such as XRD, FTIR, UV–vis, SEM, and EDX, were utilized to describe the specimen's structural, optical, and electrical properties. XRD analysis was used to confirm that the ZnO NPs were crystalline. An absorbance peak at 401 nm was observed in the UV–vis, indicating that the ZnO NPs have a 2.91 eV bandgap. Functional groups are present in ZnO NPs, as seen by the FTIR graph. The nanoparticles' spherical form and average size of 37.9 nm were confirmed by the SEM image. EDX analysis confirmed the composition of the nanoparticles, with zinc accounting for 73.17% and oxygen for 26.83%. ZnO NPs demonstrated excellent electrical conductivity because of their higher surface-to-volume ratio. Additionally, the synthesis of ZnO NPs exhibited effective degradation of methylene blue dye. These results point to potential applications in several domains, including electronics, biomedical devices, industry, and agriculture, and they call for immediate follow-up research.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"3 3","pages":"Article 100105"},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773045X24000165/pdfft?md5=694b8a30b8b6232e98fb18669ace6289&pid=1-s2.0-S2773045X24000165-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141052514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, with breast cancer as a model, microRNA 21 could trigger the self-disassembly of DNA nanowheel 1 <em>via</em> hybridization with a specially designed oligonucleotide (anti-microRNA 21) in DNA nanowheel 1, releasing another special oligonucleotide (Contact sequence) to trigger the self-disassembly of DNA nanowheel 2 with releasing of a special oligonucleotide (anti-Contact sequence) to trigger the self-disassembly of DNA nanowheel 1 cyclically, and thus the cascaded hybridization reactions with three-in-one anti-cancer functions could be generated based on three main therapeutic effects <em>via</em> releasing doxorubicin to inhibit macromolecular biosynthesis, antisense oligonucleotide of microRNA 21 to activate the apoptotic cell pathway and antisense oligonucleotide of MDR1 to prevent the drug resistance respectively. As expected, the proposed method showed improved therapeutic efficacy on the cancer cells with about 80% apoptosis ratio, especially on the drug resistant cancer cells with about 75% apoptosis ratio, compared with that in the conventional anti-cancer systems of about 70% on cancer cells and below 40% on drug resistant cancer cells, respectively.

The resistance of the pencil traces decreased from 100 kΩ to 5 kΩ as the pencil grade shifted from HB to 8B. Concurrently, capacitance measurements revealed an increase from approximately 5 pF for a 5-finger IDC made with HB pencil to around 32 pF for an 8B pencil counterpart. Increasing the number of pencil traces from 10 to 50 resulted in a significant decrease in resistance and a proportional increase in capacitance. Application of the IDC sensor demonstrated notable changes in capacitance upon proximity and touch, with a significant decrease upon removal. The interdigitated capacitance sensor exhibits good proximity effects and contact sensitivity in touch, with capacitance increasing exponentially from 0.3 pF (7 cm) to 1.2 pF (direct contact), highlighting its ability to detect objects with high precision.
