Among these NPs, gold nanoparticles (AuNPs) have attracted significant attention and are highly being utilized in several fields due to their exceptional properties. Gold nanoparticles were an emerging subject of intensive research due to their spherical shape, large specific surface area, and quick modification by functional groups. As the demand for AuNPs continuously increases; therefore, there is a pressing need to optimize the scientific approach to fully comprehend and exploit their potential. The effect of AuNPs on plant growth and development can either be beneficial or harmful, depending on the plant species and the concentration of NPs. Moderate concentrations of AuNPs have been found to induce primary and lateral roots, reduce oxidative stress, and elongate rosette diameter, while a higher concentration showed negative effects on plant growth and development. Gold nanoparticles also exhibit potent antibacterial, antiviral, and anticancer properties, making them most beneficial in various sectors, especially in the biomedical field. AuNPs are extensively being utilized across various sectors, but their application in the biomedical field is noteworthy, particularly in bioimaging, biosensing, targeted gene and drug delivery, theranostics, regenerative medicine, and tissue engineering. This review emphasizes the potential applications of AuNPs in diverse sectors including agriculture and biomedical, highlighting their potential impact (positive and negative) on plant growth. Furthermore, the review also aims to signify the mechanism of action of AuNPs and their efficacy against bacteria, viruses, and cancer cells.","PeriodicalId":23847,"journal":{"name":"Zeitschrift für Physikalische Chemie","volume":"16 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139607982","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}

Perlite is a cheap and abundant adsorbent and it can be used for versatile applications in food, pharmacy and chemistry industries. Perlite was chosen for the removal of penta chloro nitrobenzene (PCNB) pesticide. This pesticide is used for the control of fungi species in farming commonly. Adsorbent surface area and pore volumes were determined as 288.15 m2/g and 78.24 cm3/g (BET method). The characteristics of the adsorbent were furnished by evaluating the SEM and FTIR images. The adsorption equilibrium was reached in 80 min. Initial adsorbate concentration and pH of the medium were also investigated from this point of view. The experimental data were evaluated with proper isotherm models such as Langmuir, Freundlich and Halsey. Langmuir and Freundlich isotherms give the best results. Monolayer capacity was found as 238.095 mg/g. The kinetic mechanisms of the phenomon was analyzed by employing the pseudo first and second order models. Pseudo first order kinetic results were better than the second one with the higher regression coefficients and close experimental and calculated uptake values. Those values were found as 0.615 and 0.6587 mg/g for 1 μg/mL aqueous pesticide solution. Activation energy was found approximately 5094 J/mol which was shown a physisorption mechanism of the adsorption. Activation energy is also employed for interpreting the sticking probability factor. The thermodynamic of adsorption were also evaluated and found as −2.385 J/g at the room temperature. The negative Gibbs energy shows the feasibility and spontaneous nature of PCNB removal on perlite.","PeriodicalId":23847,"journal":{"name":"Zeitschrift für Physikalische Chemie","volume":"47 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139612253","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}

Nevertheless, the challenges regarding siRNA delivery for cancer therapy remain a major concern for taking these therapies successfully from laboratory to in vivo studies. Biomaterials are defined traditionally as any material that is used for either medical or dental applications that contact the host cells in any form, such as a drug carrier a device, or as a prosthesis towards the replacement of damaged tissues. The main issues to be fulfilled by the biomaterial for clinical applications are biocompatibility, bioactivity, ability to carry drug to target site, inflammatory responses and other factors based on its application. The present study focuses on the in vitro inflammatory response to the CS nanoparticles using RAW 264.7 and bone marrow derived macrophage cells. Additionally, the in vitro release kinetics of siRNA with varying concentrations and pH, transfection efficacy and biocompatibility were also investigated. The results of siRNA cumulative release increased at pH 5 and 3, which may be corresponding to the protonation, and a delayed release was seen at 7, which was ascribed to unprotonated amine groups inside the CS. The results of release kinetics confirmed a sustained release of siRNA from CS NPs. Considering that CS is a biocompatible polymer, it typically has little impact/damage on cells, as numerous researchers have observed during in vitro experiments. Inflammatory studies were carried out in vitro with RAW 264.7 and BMC cells derived from mice. The gene and protein expression studies showed that the materials might cause some slight inflammation on exposure with both RAW 264.7 and BMC cells in vitro, which is completely negligible. However, putting together the overall data it can be concluded that CS NPs can be a promising material for in vivo applications, which is in agreement with the results of other researchers, but the only concern being its ability to carry siRNA and protect it from nuclease and other enzymatic attacks.","PeriodicalId":23847,"journal":{"name":"Zeitschrift für Physikalische Chemie","volume":"13 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139380025","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}
