The clay mineral montmorillonite is predominantly responsible for soil expansion. Because of their ability to shrink and swell with seasonal changes in moisture content, these expansive soils can cause significant damage to engineering construction. To stabilize the effects of swelling soil various ground improvement techniques, incorporate mineralogical modification of clays. The application of nanotechnology increased in past few years to deal with clay minerals as it possesses the same dimensional properties. To understand the behaviour of Nano modified clay, bentonite was selected as it represents the montmorillonite clay mineral. The characterization of surface-treated bentonite by nanomaterial was carried out. The study of physio-chemical properties and textural properties of surface-modified bentonite clay was carried out. Swelling pressure was evaluated by a consolidometer test. With the advanced nanotechnology instrumentation technique, particle size analysis, zeta potential, wettability, contact angle, infra-red spectroscopy, rheological properties, BET surface area, pH values, XRD, TGA, etc was carried out for treated and untreated soil, to understand the comparative behaviour of surface modification. It was found that by using Nano surfactant, liquid limit and shrinkage limit were reduced considerably. The increase in the quantity of surfactant increases the d-spacing. Thermal stability and particle size increase after surface treatment of bentonite clay. Soil reaches a visco-elastic state and BET surface area decreased after surface modification.","PeriodicalId":7359,"journal":{"name":"Advances in Natural Sciences: Nanoscience and Nanotechnology","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132958","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, difficulty in their delivery has limited their use. In particular, their oral bioavailability and stability is very low, and non-invasive drug delivery route such as nasal, pulmonary and transdermal delivery faces absorption limitations. Therefore, the promising way of protein-based drug delivery is parenteral route. However, this route also has some problems like poor patient compliance, pain, and dermal discomfort. So, structure based nanocarriers design for drug delivery is developing nowadays and has illustrated the fewer side effects and better usefulness in disease treatment than free drug molecules. A modish nanocarriers offer site specific drug delivery in controlled fashion against all the physiological barriers and is ultimately metabolized in the body. This review will discuss the various nano-formulation strategies for biomacromolecules delivery.","PeriodicalId":7359,"journal":{"name":"Advances in Natural Sciences: Nanoscience and Nanotechnology","volume":"70 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132960","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 aqueous leaf extract of Thymus vulgaris was used in the current investigation to achieve the biosynthesis of TiO2 nanoparticles (TiO2 NPs). In this study, leaf extract was used as a size-reducer in synthesis of TiO2. Thyme leaf extract contains flavonoids, phenols, and saponins, which function as both reducing and stabilising agents and are crucial for the synthesis of TiO2 nanoparticles. Methods such as Fourier-transform infrared spectroscopy (FTIR), ultraviolet-visible diffuse reflectance spectroscopy (UV-DRS), x-ray diffraction (XRD), photoluminescence (PL), and scanning electron microscopy (SEM) with energy dispersive x-ray (EDX) were used to characterise TiO2 NPs. The XRD investigations showed that titanium dioxide nanoparticles are crystalline and average crystal size is 28 nm. Gram-positive bacteria like S. aureus and B. subtilis as well as Gram-negative bacteria like Pseudomonas aeruginosa were used as standardised test microbial inoculums to evaluate the antibacterial properties of biosynthesised nanoparticles (TiO2 NPs). Against each of the studied bacteria, the TiO2 nanoparticles demonstrated significant antimicrobial activity. TiO2 nanoparticles had the maximum activity against Staphylococcus aureus, with an inhibitory zone diameter of 14 mm at 100 g ml−1. By using DPPH, hydroxyl radical techniques, the comprehensive antioxidant activity of produced NPs was examined.","PeriodicalId":7359,"journal":{"name":"Advances in Natural Sciences: Nanoscience and Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47754112","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 study investigates the effects of different acid types and concentrations, as well as aging times, to determine the optimal conditions for preparing nanosilica from sugarcane bagasse ash (SCBA). Nanosilica synthesised with citric acid exhibits a higher specific surface area (554.01 m2 g−1) and yield (88.54%) compared to those synthesised with sulfuric, oxalic, and acetic acids. X-ray diffraction (XRD) patterns and transmission electron microscope (TEM) images show that the synthesised nanosilica has an amorphous silica phase with a particle diameter of approximately 5.6 nm. The applicability of the synthesised nanosilica as an adsorbent for methylene blue (MB) is studied. Various conditions such as adsorbent dosage, contact time, and initial concentration of MB are evaluated. The results reveal that the synthesised nanosilica has a high adsorption capacity (232.29 mg g−1) and removal efficiency (R%) of 90% for MB. The experimental results align with the Freundlich model and can be used for effective dye removal. The development of a simple and environmentally friendly method for synthesising nanosilica with superior adsorption properties is an important contribution to the field of waste management and provides a useful tool for tackling environmental pollution caused by organic dyes.","PeriodicalId":7359,"journal":{"name":"Advances in Natural Sciences: Nanoscience and Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47260455","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 study provides a novel, simple, cost-effective, and environmentally friendly approach for the production of zinc oxide (ZnO) nanoparticles (NPs) as a promising photocatalyst through the reduction of zinc nitrate hexahydrate using a leaf extract of Piper betle (P. betle). The wurtzite hexagonal structure of ZnO, with a crystallite diameter of 43.44 nm and an energy band gap of 2.97 eV, was seen in P. betle/ZnO. The Fourier transform infrared (FTIR) study showed that phytochemicals from the P. betle extract were present on the surface of P. betle/ZnO. The high-resolution transmission electron microscopy (HRTEM) and field emission scanning electron microscopy (FESEM) analyses revealed the existence of multiple structures scattered evenly (spherical, hexagonal, and rod-shaped). The BET findings indicate that P. betle/ZnO NPs have a highly porous structure with a significant surface area of 97.11 m2/g. The degradation of commercial dye was employed to evaluate the photocatalytic capability of P. betle/ZnO. With ultraviolet radiation, the removal percentage of light green dye might surpass 99% in 80 min with a degradation rate of 2.58 × 10−2 min−1. It was observed that the degradation kinetics follow pseudo-first-order kinetics. P. betle/ZnO is acknowledged as an effective photocatalyst for the treatment of commercial effluent.","PeriodicalId":7359,"journal":{"name":"Advances in Natural Sciences: Nanoscience and Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45599319","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}

It exhibits anti-inflammatory, anti-oxidant, anti-cancer, anti-microbial effects and is used for the treatment of several diseases like cancer, cardiovascular ailments, and microbial infections. The major limitations of quercetin are low water solubility, less chemical stability, low bioavailability, and short biological half-life. All these major drawbacks can be overcome by its encapsulation in various nanocarriers (nanoparticles, nanoliposomes, nanocrystals, nanomicelles, etc). Such quercetin encapsulated nanoformulations displayed enhanced solubility, stability, bioavailability, high encapsulation efficiency, controlled drug release and extended systemic circulation time period. Quercetin loaded nanocarriers can easily pass across different barriers like blood brain barrier (BBB), skin barriers, mucosal membrane, hence providing target site specific delivery. They also exhibited improved therapeutic effects such as enhanced anti-cancer, anti-diabetic, anti-microbial, anti-inflammatory, anti-psoriasis, anti-oxidant, anti-asthmatic, anti-acne, skin-whitening, hepatoprotective, photoprotective, neuroprotective, nephroprotective and cardioprotective actions. Major health issues associated with nanoformulations are risk of cytotoxicity, oxidative stress, DNA damage, and mutations that can be minimised with continual advancements in nanotechniques. The present review discusses quercetin, its historical background, pharmacokinetics, mechanism of action, and therapeutic applications with major emphasis on the quercetin nanoformulations such as nanoparticles, nanoemulsions, nanoliposomes, nanocrystals, nanosuspensions and nanomicelles that enhances its physicochemical stability, solubility, and therapeutic applications.

Due to the fast spread of waterborne and food borne infections in society and the high costs associated with them, pathogen identification has emerged as one of the most difficult parts of the water and food sectors. Since the turn of the century, pathogens have demonstrated enormous epidemiological and pandemic potential. The emergence and dissemination of a novel virus with pandemic potential endanger the livelihoods and well-being of individuals worldwide. The severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) coronavirus pandemic has propagated to almost every country on Earth and has had a considerable negative influence on economies and communities. Despite improvements in identification techniques for viral diseases, all nations must now execute biosensing in a speedy, sensitive, focused, and consistent manner in order to address pressing global issues. Hence, in this review, we have critically summarised the recent advancement of electrochemical as well as optical biosensors for the monitoring of SARS-COV-2 and various pathogens. Then, we began by providing a technical overview of cutting-edge strategies utilised to combat diseases and emergencies for it, including the utilisation of point-of-care technology (POCT), artificial intelligence (AI), and the internet of medical things (IoMT). This review article explores the integration of POC, IoMT, and AI technologies in the context of personal healthcare, focusing on their potential to expedite the diagnosis and treatment of medical conditions, ultimately leading to improved patient outcomes. Subsequently, the notion and execution of multiplex testing are presented to enhance the comprehension of detecting multiple analytes.
