Green nanoparticles represent a revolution in bionanotechnology, providing opportunities to fight life-threatening diseases, such as cancer, with less risk the environment and human health. Here, for first time, we systematically investigated anticancer activity possible mechanism of novel silver (N-SNPs) synthesized by Nostoc Bahar M against MCF-7 breast cancer cells, HCT-116 colorectal adenocarcinoma HepG2 liver using cell viability assays, morphological characterization inverted light...
Over recent years, green chemistry procedures have been developed to synthesize nanoparticles in eco-friendlier and less expensive ways. These use natural sources such as bacteria, fungi, yeast, plants, actinomycetes, algae, or cyanobacteria, biomolecules proteins, vitamins, pigments instead of chemical materials fabricate salt precursors into nanoparticles.In the current investigation, we an effective, inexpensive, nontoxic method silver (SNPs) using cellular extract a novel strain...
Among various routes of metallic nanoparticle (NPs) fabrication, phytosynthesis has significant advantages over other conventional approaches. Plant-mediated synthesis NPs is a fast, one-step, ecobenign, and inexpensive method with high scalability. Herein, silver (Ag) gold (Au)-NPs were extracellularly synthesized using aqueous Haloxylon salicornicum (H@Ag-, H@Au-NPs) leaf extracts. GC-MS was performed to analyze the chemical compositions H. extract. H@Ag- H@Au-NPs characterized via UV-Vis...
Severe destructive hepatic injuries can be induced by acetaminophen overdose and may lead to acute failure.To investigate the ameliorative effects of Arctium lappa root extract on acetaminophen-induced hepatotoxicity.Rats were divided into 4 groups: normal control group, acetaminophen-injected treated with group.The treatment reduced serum alanine transaminase, aspartate aminotransferase, alkaline phosphatase in group when compared group. DNA fragments also significantly increased (P <...
Algal-mediated synthesis of nanoparticles (NPs) opens the horizon for green and sustainable NPs that can be used in many fields, such as medicine industry. We extracellularly synthesized silver (Ag-NPs) using novel microalgae Planophila laetevirens under optimized conditions. The isolate was collected from freshwater/soil, purified, morphologically identified, genetically identified light, inverted scanning electron microscopy, 18S rRNA sequencing. phytochemicals algal extract were detected...
Algal-mediated synthesis of nanoparticles (NPs) is an eco-friendly alternative for producing NPs with potent physicochemical and biological properties. Microalgae represent ideal bio-nanofactory because they contain several biomolecules acting as passivation stabilising agents during the biogenesis NPs. Herein, a novel microalgae sp. was isolated, purified, identified using light electron microscopy 18s rRNA sequencing. The chemical components their watery extract were assessed GC-MS. Their...
Phormidesmis communis strain AB_11_10 was isolated and identified using microscopy 16s rRNA sequencing, its phytochemical constituents were determined liquid chromatography-quadrupole time-of-flight mass spectrometry. The isolate had a segmented filamentous shape with blue-green color. Many biomolecules, including organic compounds, amino acids, fatty detected. P. used to synthesize gold nanoparticles (Ph-AuNPs) by adjusting the optimum reaction conditions. concentration, algal/precursor...
Microalgae-mediated nanoparticle (NP) biosynthesis is a promising green synthesis method that overcomes the challenges of conventional methods. The novel Desmochloris edaphica strain CCAP 6006/5 was isolated, purified, and characterized morphologically genetically.
