Nanomaterials have provided promising results as mimic catalysts termed nanozymes (NZMs). This article briefs the peroxidase mimicking behavior of Oxalic acid-capped WO₃ nanoparticles (Ox-WO₃ NPs), which were hydrothermally synthesized. The peroxidase parodying behavior of the synthesized NZMs was studied for H₂O₂ as substrate and PPDD-NEDA and TMB as a chromogenic reagent in Phosphate buffer at pH 6.5. The coupled product of PPDD-NEDA showed λ_max=480 nm, and the method was linear between 0.2413 and 1.93 mM. The oxidized product of TMB λ_max=650 nm was linear in the range of 0.1938–1.9386 mM. K_m values corresponding to TMB, and PPDD-NEDA were 0.5308 and 0.3957 mM. Kinetic constants with respect to PPDD-NEDA i.e., V_max, K_cat, K_eff, and K_pow were found to be 0.1913 mM/min, 3.3639 min⁻¹, 8.4999 mM⁻¹ min⁻¹, and 0.4833 min⁻¹. The precision study for intra-day (1.27–2.49 %) and inter-day (1.09–1.52 %) has been calculated. LOD and LOQ of the reaction was found to be 56.34 and 170.73 µM respectively. Characterization of synthesized NPs were carried out with respect to morphology, crystallinity, size, zeta potential and others. The XRD of the sample revealed the crystallite size to be 42.6 nm (Williamson-Hall equation) and 35 nm (Scherrer equation), Crystal structure was identified to be a mixture of monoclinic and orthorhombic as compared with the JCPDS file and the crystallinity of the sample was found to be 79.75 %. The SEM images provided the morphology to be spherical in nature with more aggregation due to lower zeta potential value as recorded by the DLS. The elemental composition by EDS recorded the formation of WO₃ NPs. The broad peak of FT-IR spectra between 2900 and 3900 cm⁻¹ confirms the capping of oxalic acid to WO₃ NPs.</div></div>","PeriodicalId":397,"journal":{"name":"Nano-Structures & Nano-Objects","volume":"40 ","pages":"Article 101340"},"PeriodicalIF":5.45,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320066","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}

This review article discusses the implementation of LIG for energy storage purposes, especially batteries. Since 1991, lithium-ion batteries have been a research subject for energy storage uses in electronics. The uneven distribution of lithium resources and rising costs hamper lithium-based battery growth. Multivalent ion batteries, or MIBs, have gained significant traction as an alternative for large-scale energy storage. Earth's crust is mainly composed of polyvalent ions, such as calcium (Ca2+), magnesium (Mg2+), aluminum (Al3+), zinc (Zn2+), etc. As a result, a lot of research has been done on lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), lithium metal batteries (LMBs), zinc blue ion batteries (ZIBs), etc. Graphite anode is more useful in these batteries due to its high theoretical capacity of 372 mAh g⁻¹ and proper stability. Recent technological breakthroughs have driven the emergence of graphene-based anodes. Graphene, a single-layer sheet of carbon atoms, offers a large surface area and can serve as a platform adaptable to many needs. There are multiple methods to produce graphene, and the League method stands out with its simplicity, effectiveness, and low cost, making it ideal for diverse applications. It also enables the creation of graphene with tunable properties. In addition, it is a green method and can reduce concerns regarding the increasing production of electronic waste. Green LIG is produced from cellulose materials such as paper and wood, which are environmentally friendly raw materials. Next, it discusses LIG's production process and the laser's critical parameters for graphene fabrication and functionalization. Following this, we delve into recent and promising research in battery research, developed using laser processing techniques, with a particular focus on battery applications. The review concludes by discussing laser technology's main challenges and Potential applications for graphene in energy device manufacturing. One of the main challenges of LIG is that it is difficult to produce thick films. Another challenge is that LIG has high resistance, which can cause ohmic loss in electronic applications. Researchers are currently working on ways to reduce the resistance of LIG without sacrificing its other useful features. Also, this factor can affect its stability and cause aging. Despite these challenges, LIG has the potential to revolutionize the way graphene electrodes are produced, sparking excitement and optimism about the outlook for energy storage solutions. LIG offers a simple, cost-effective approach to producing graphene electrodes with customizable properties, making it a promising candidate to revolutionize the field.</div></div>","PeriodicalId":397,"journal":{"name":"Nano-Structures & Nano-Objects","volume":"40 ","pages":"Article 101347"},"PeriodicalIF":5.45,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142314128","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}

The prevalence of HCC is increasing day by day &amp; complicated health status. Presently, there are different treatment strategies for overcoming HCC. But none of them are stable enough to overcome this permanently. The failure of treatment has abundant reasons, such as inadequate pharmacokinetics and pharmacodynamics features of existing treatment, low drug targeting, drug resistance, and so on. Therefore, researchers have investigated various nano-structured gold to diagnose and treat HCC. Concerning this concept, gold nanoparticles (AuNPs) have shown tremendous potential in synergizing chemotherapy and have unique intrinsic theragnostic properties. These nano-golds enhance the retention of the therapeutics in the tumor cells due to the enhanced permeability and retention (EPR) effect. The EPR effect can increase the permeability effect through different membranes, and thereby, the nano-gold can strike the specific area successfully. In the field of biomedicine, particularly in drug delivery, molecular imaging, and cancer treatment, nano-structured golds are extensively utilized. This evidence indicates that AuNPs decrease the proliferation of cancer cells and ultimately reduce the chances of cancer metastasis. This review will further focus on the theragnostic applications of gold nanoparticles, including their synthesis and applications to mitigate HCC and other malignancies.

The inherent inadequacies of traditional medicines in terms of tumour selectivity and undesired toxicity urge us to seek alternative therapies to address these drawbacks. Metal<img>organic frameworks (MOFs) have been synthesized for use in drug delivery systems (DDS) because of their improved porosity and larger specific surface area. In this research, UiO-66-NH₂ MOFs were synthesized via a solvothermal technique and functionalized with chitosan-folic acid (CS-FA) as a DDS for targeted doxorubicin (DOX) delivery. The MOF nanoplatforms were characterized via different techniques, including FTIR, PXRD, BET, TEM, DLS, TGA, SEM, and TGA. Remarkably, compared with the unmodified MOF, UiO-DOX@CS-FA delayed DOX release due to a gated effect induced by the CS-FA surface coating. pH-sensitive DOX release was observed, where 39.76 % of the drug was released in the tumour-mimicking pH of 5.2, whereas 5.84 % of the drug was released at physiological pH (7.4). In vitro cellular toxicity and uptake investigations demonstrated that UiO-DOX@CS-FA is a highly effective targeted DDS against MCF-7 breast cancer cells. Furthermore, in vivo toxicity studies in Wistar rats revealed no evidence of serious adverse effects. The variety of pharmacokinetic characteristics tested indicated that the bioavailability and release kinetics of DOX improved.
