Titanium nanoparticles (TiNPs) have been synthesized due to its certain characteristics that are expected like non-toxic, eco-friendly, and bioactivity. In this study, the researchers used Banana Peels Extract (BPE) with titanium dioxide to prepare new nanoparticles which are never carried before. These nanoparticles were biologically synthesized using an aqueous solution of banana peel extract as a bioreductant. The novel TiNPs were successfully prepared and characterized using Ultraviolet-Visible Spectroscopy (UV-VIS), Atomic Force Microscopy (AFM), X-Ray Diffractometer (XRD), and examined its antimicrobial activity against several pathogenic bacteria as well as insecticidal agent against Musca domestica. The instrumental analysis confirms the presence of TiNPs with average diameter: 88.45 nm and volume 31.5 nm as resulted by AFM and XRD respectively, while the bioactivity exam to TiNPs shows inhibitory effect against several pathogenic bacteria, as well as it cause a high mortality percentage against three larval stages of house fly.
The green plant-mediated synthesis of iron nanoparticles (GPS-Fe) nanoparticles (NPs) has become more and more popular. In this study, fresh rosemary leaf aqueous extracts that decreased aqueous silver nitrate were used to demonstrate the synthesis of FeNPs. This procedure allowed for the synthesis of NPs that were examined using a different of analytical techniques, including transmission electron microscopy (SEM), energy-dispersive X-ray spectroscopy, FTIR, ultraviolet-visible (UV-Vis) spectrophotometry, and studies on dynamic light scattering. According to ocular observation and UV-Vis spectra, fresh leaf extract treatment changed the color of aqueous ferric nitrate to a bluish hue. Additionally, the TEM analysis revealed that the synthesized NPs were evenly dispersed and had average sizes less than 65 nm. Meanwhile, the bioactivity test shows that the NPs had an inhibitory effect on a number of pathogenic bacteria and caused a high rate of mortality in three stages of house fly larvae.
The importance of this appraisal is on the utilization and possible of entomopathogenic roundworms (EPNs) as biotic regulator factors in maintainable nutrition manufacture transversely an extensive variety of agronomic and extra supplies. To help by the consideration of the possibility of EPNs in supportable nutriment construction, this evaluation to offers impressions on EPN biology and environmental science, conglomerate manufacture and implementation expertise, and communications through additional organization gears. Primary find out in the 1920s, their trade as biopesticides in the 1980s was attended and pursued via exponential development in investigate on their implementation, biology, and ecosystem sought via a more increase in extra rudimentary investigate regions then the middle-2000s. This assessment précises important advancement completes in the study and implementation of EPN in insect pest administration in significant nutrition yields inclusive groves, minor fruitiness, corn, vegetative, corm yields, glasshouses, and bourgeons. Noteworthy agents impacting the achievement of EPN caramelization are similarly argued. An increasing benefit in substitutes to artificial insecticides and in biological cultivation unbolts chances intended for EPNs, nonetheless, EPNs will necessity to be additionally enhanced by a concern to effectiveness, decreased charges, and facility of utilizing. Furthermore, they're probable to reprocess harbor inhabitants and seduce them to be more invested for an extended period of pest repression.
Background: Lawasonia Inermis (henna) extract and trillium dioxide (TeO2) has many applications among them is biomedicine and pharmaceutical industry. Objective: the current study aimed to prepare extract from henna leaves, and synthesize novel nanoparticles derived from henna extract and TeO2, characterized them and test its bioactivity against house flies. Materials and Methods: Lawasonia Inermis (henna) leaves and TeO2 were collected from local markets in Baghdad, Iraq. The extraction of henna leaves was prepared and the TeO2nano particles was synthesized according to a certain procedures, the nanoparticles of the combination of henna extract and TeO2 was prepared a characterized successfully using different techniques such UV-Vis, XRD, AFM. The bioactivity of all the compounds was evaluated and tested. Results: The UV-Vis, XRD and AFM spectra was collected and evaluated. The bioactivity was also examined against house fly and the collected data was clear and very optimistic. It was found that the highest effect was of trillium nanoparticles prepared at a concentration of 500ppm to reach 100% to kill the 1st larval. It also shows clear decreases in the effect at the same concentration above for the 1st larval stage when using only trillium oxide or only henna leaves extract, 30% and 10% respectively, Conclusions: Many conclusions were found in this work, among them are; extract of Lawasonia Inermis leaves was prepared successfully, novel nanoparticles were synthesized from henna extract and TeO2 nanoparticles (HennaTeO2NPs) was prepared, characterization of the novel hennaTeO2NPs was carried out, and the bioactivity of the novel nanoparticles was carried out against house fly and it was noticed that the novel henna nanoparticles shows best activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
