Plumeria alba flower extract-mediated synthesis of recyclable chitosan-coated cadmium nanoparticles for pest control and dye degradation.

In the current scenario, many synthetic chemicals have used long-term to control pests and mosquitoes, leading to the resistance of strains and toxicity effect on human beings. To overcome the adverse problem in recent advances, the scientific community is looking into nanofabricated pesticides and mosquitoes. This study aims to synthesize the recyclable chitosan-coated cadmium nanoparticles (Ch-CdNps) using Plumeria alba flower extract, which was further applied for insecticidal and mosquitocidal activities.

Biosynthesis, characterization, and antibacterial activity of gold nanoparticles.

Background: In recent decades focus of research has been toward an alternative antibacterial agent because of growing bacterial resistance and side effects of antibacterial agents. In the current study, the antibacterial activity of gold nanoparticles has been evaluated on selected human pathogens.

Methods: In this study, we used panchagavya (PG) to synthesize gold nanoparticles, and the resulting nanoparticles (PG-AuNPs) were characterized by several spectroscopic techniques.

Isolation of bioactive compounds from lichen Parmelia sulcata and evaluation of antimicrobial property.

Background: Lichens were used as an ailment in the traditional medicine for treating various disorders for centuries. Since there is less evidence in the literature about the medicinal property of Parmelia sulcata (P. sulcata), we made a pioneer attempt to explore the antioxidant and antimicrobial properties of lichens.

Nanosilver reinforced Parmelia sulcata extract efficiently induces apoptosis and inhibits proliferative signalling in MCF-7 cells.

The Lichen, Parmelia sulcata synthesizes various secondary metabolites, in which phenolic based compounds received much attention due to their importance in biomedical application. Especially the phenolic compound was effective against the cancer treatment. An effective administration of such plant natural product can represent a significant conventional management of cancer in terms of chemoprevention.

Studies on the spectrometric analysis of metallic silver nanoparticles (Ag NPs) using Basella alba leaf for the antibacterial activities.

In this present investigation, an aqueous Basella alba leaves extract was used to synthesize AgNPs. The green synthesis approach is carried out in our work due to non-toxic, less cost, and ecofriendly methods. FTIR spectra are used to confirm the biomolecules present in B.

Lichen Parmelia sulcata mediated synthesis of gold nanoparticles: an eco-friendly tool against Anopheles stephensi and Aedes aegypti.

The gold nanoparticles (AuNPs) were synthesized using the lichen Parmelia sulcata extract (PSE) and characterized. The peaks of ultraviolet spectrophotometer and Fourier transmission infrared confirmed the formation of nanoparticles and the bioactive compounds of the lichen being responsible for reducing and capping of the particles. The face-centered cubic particles were determined by XRD peaks at 111, 200, 220, and 311.

Development and quantification of biodiesel production from chicken feather meal as a cost-effective feedstock by using green technology.

Increased urbanization and increase in population has led to an increased demand for fuels. The result is the prices of fuels are reaching new heights every day. Using low-cost feedstocks such as rendered animal fats in biodiesel production will reduce biodiesel expenditures.

Synthesis, characterization and evaluation of antimicrobial efficacy and brine shrimp lethality assay of stem bark extract mediated ZnONPs.

is one of the most important medicinal plants and herein, we present the synthesis of zinc oxide nanoparticles using the bark extract of and evaluation of their antimicrobial efficacy. Stable ZnO nanoparticles were formed by treating 90 mL of 1 mM zinc nitrate aqueous solution with 10 mL of 10% bark extract. The formation of bark extract mediated zinc oxide nanoparticles was confirmed by UV-visible spectroscopic analysis and recorded the localized surface plasmon resonance (LSPR) at 430 nm.

anti- biofilm and anti-bacterial activity of extract against .

The main objective of this research is to investigate the anti-biofilm and anti-bacterial activity of ( extract were prepared and analyzed with UV -Vis spectroscopy, Fourier transform infrared spectroscopy, Dynamic light scattering. Biofilm forming pathogens were identified by congo-red assay. Quantification of Extracellular polymeric substance (EPS) particularly protein and carbohydrate were calculated.
