Traditional cancer diagnosis methods are somewhat limited and are unable to meet existing needs; consequently, DNA nanostructures with wide ranging properties are receiving increasingly more attention because a number of DNA materials have been shown to exhibit diagnostic properties. Some DNA materials can functionally alter the biological behavior of cells, such as cell migration, cell proliferation, cell differentiation, autophagy, and anti-inflammatory effects. Some single-stranded DNA or ribonucleic acid with secondary structure through self-pairing, called aptamer, systematic evolution of ligands by exponential enrichment (SELEX), have targeting capabilities and can be applied to tumor targeted diagnosis and therapy. Several DNA nanomaterials with three-dimensional nanostructures and stable structures are being investigated as drug carrier systems to act on a variety of antitumor drugs or gene therapy agents. This article reviews the use of functionalized DNA nanostructures in cancer diagnosis and treatment applications. Various biosensors and carriers based on DNA nanostructures are introduced and chemical reactions related to the preparation of the carrier and the signal transduction mechanism of the sensor are discussed. Efficient carrier/biosensor platforms based on various structural developments and current DNA nanomaterial developments are also presented.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135009503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comprehensive analyses were performed to characterize the composition, structure, and morphology of the synthesized material. X-ray diffraction results confirmed the successful inclusion of Co in the NiWO 4 lattice, with the presence of characteristic peaks of CoWO 4 . The crystallite size, determined using the Scherrer equation, was measured to be 22 nm. Using UV-Vis spectroscopy and Tauc’s equation, we calculated the band gap energy ( E g ) to be 3.75 eV for NiWO 4 and 1.75 eV for Co–NiWO 4 . The potential application of the synthesized material as a photocatalyst was investigated for the degradation of the diazo dye Congo red (CR). Under optimized reaction conditions, Co–NiWO 4 NPs demonstrated outstanding efficiency, degrading a total of 95% of CR. The degradation kinetics were well-described by the Langmuir–Hinshelwood (L–H) kinetic model, indicating that photoabsorption played a crucial role in the rate-controlling step. These encouraging results suggest that Co–NiWO 4 NPs hold promise as a viable option for addressing other pollutants in various applications.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135101826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, dusty fluids are used in gas-freezing systems and nuclear power reactors. The main objective of this article is to focus on the characterization of generalized two-phase free convection magnetohydrodynamic flow of dusty tetra-hybrid Casson nanofluid among parallel microplates: dusty Casson fluid and tetra-hybrid nanofluid exhibit free movement and electrical conductivity. The Caputo–Fabrizio fractional derivative recently discovered generalizes the partial differential equations governing the flow. Highly accurate temperature and velocity distributions can be obtained using finite sine Fourier and Laplace transform together. This study examines the relationships between temperature, dust particle velocity, and Casson fluid velocity, along with the effects of magnetic parameter, Grashof number, dusty fluid parameter, Peclet number, Reynold number, and particle mass parameter. The Mathcad-15 software provides Casson, dusty, and temperature profiles graphically. The Nusselt number and skin friction are also examined for the tetra-hybrid nanofluid. The fractional Casson fluid model is more accurate than the classical model in terms of velocity, temperature, heat transfer, and skin friction. Graphical results conclude that the fractional Casson fluid model describes a more realistic aspect of both (fluid and dust particle) velocities and temperature profiles, heat transfer rate, and skin friction than the classical Casson fluid model. Furthermore, the heat transfer rate enhanced from 0 to 39.3111% of the tetra-hybrid nanofluid.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135494832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From an environmental perspective, alumina nanoclusters dispersed on surfaces of particulate matter PM12, generated from various combustion processes, play a critical role in the synthesis of environmentally persistent free radicals (EPFRs). Of particular importance are phenoxy-type EPFRs that often act as building blocks for the formation of notorious pollutants. Herein, we present a systematic review of the literature pertinent to structural features of alumina surfaces at the nano-scale and their well-established role in the synthesis of EPFRs. Central to the capacity of alumina surfaces in mediating the formation of EPFRs are their active Lewis acid–base sites. The nature of these sites is very sensitive to hydration scenarios. As evident in electroparamagnetic resonance measurements, more than one category of EPFR forms on alumina surfaces. This generally entails the co-existence of various surface terminations, varying degrees of hydrations, and distinct underlying reaction pathways. The mechanisms for the formation of EPFRs over alumina surfaces involve interactions with terminal OH groups followed by creating genuine chemical bonds with Al3+ sites. Higher concentrations of EPFRs were often detected on alumina surfaces, in reference to other transition metal oxides. We envisage that future studies may focus on the generation of EPFRs from potential precursors other than phenols and catechol, such as brominated species and substituted thiophenols.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":" ","pages":""},"PeriodicalIF":7.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46087108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polyurea with tunable chemical and morphological structure are of interesting polymers to prepare micro-/nano-capsules used in construction. The structure of polyurea micro-/nano-capsule is capable to be tailored via bulk emulsion or microfluidic method. Important factors for production of micro/nano-capsules are the rate of fabrication and having control over mean size, dispersity, and wall thickness. The bulk emulsion method provides higher yield of production with less control over sizes and dispersity in comparison to microfluidic technique. The main applications of polyurea micro-/nano-capsules in construction industries are categorized as thermal energy saving, self-healing concrete, self-healing polymers, and fire retarding. Polyurea showed appropriate thermal conductivity and mechanical properties which is required for encapsulation of phase change materials. Titanium dioxide polyurea microcapsules possess energy storage efficiency of 77.3% and thermal storage capacity of 99.9%. Polyurea microcapsules with sodium silicate cargo provided self-healing abilities for oil well cement in high temperature and showed higher self-healing abilities compared to gelatin microcapsules. Graphene oxide polyurea micro-/nano-capsules demonstrated 62.5% anti-corrosive self-healing efficiency in epoxy coating, and steel coated via dendritic polyurea microcapsules embedded polyurethane remained unchanged after long time immersion in salt water.","PeriodicalId":18839,"journal":{"name":"Nanotechnology Reviews","volume":" ","pages":""},"PeriodicalIF":7.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44485840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
