Zinc ferrite (ZnFe2O4) magnetic nanoparticles (NPs) were important due to their biological applications. In this work, zinc ferrite nanoparticles were synthesised by green method using Aegle marmelos leaves extract antimicrobial activity and drug delivery were studied. The synthesized magnetic nanoparticles were characterized by powder x-ray diffraction method (XRD), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy (FE-SEM). XRD pattern of the synthesised ferrite samples showed cubic structure and matched with JCPDS no: 82-1042. FTIR spectroscopy revealed the characteristic functional group of ferrite nanoparticles. Magnetic properties of synthesised ferrite nanoparticles were studied using VSM. Agglomerated and irregular shaped particles were noticed from SEM. The synthesized ZnFe2O4 nanoparticles released 95% of carfilzomib (cancer drug) drug in 360 min. Furthermore, antibacterial activity was studied by well diffusion method against Escherichia coli (17 nm), Pseudomonas aeruginosa (25 nm), and Staphylococcus aureus (22 nm) and Bacillus subtilis (23 nm). Higher zone of inhibition was noted against pseudomonas aeruginosa compared to other organisms. © 2018 IOP Publishing Ltd.

Lymphatic Filariasis

Nanopesticides: A Boon Towards the Control of Dreadful Vectors of Lymphatic Filariasis

The sustainable synthesis of nanoparticles provides an eco-friendly and interesting approach in the domain of clean synthesis and nanobiotechnology. The in vitro synthesis of silver nanoparticles from the aqueous extract of an indigenous South African plant: Ekebergia capensis is reported in this paper. The rapid fabrication of Ag NPs were observed by visual colour and was confirmed using UV spectroscopy; the emergence of a yellow–brownish colour confirmed the yield of silver nanoparticles. Also, a time course study on the effect of concentration of AgNO3 was undertaken. The synthesized Ag NPs was characterized by TEM, XRD, and DLS whilst, FTIR and GC–MS provided information on the functional groups adhered to the surface of the Ag NPs. The XRD peak of synthesized Ag NPs showed their crystalline structure. DLS and TEM studies revealed spherical or near spherically shaped Ag NPs of particle size 20–120 nm. Furthermore, the catalytic performance of Ag NPs in the degradation of Allura red (AR) and Congo red (CR) were characterised by UV spectrophotometry. The Silver nanoparticles were observed to have excellent catalytic properties on the degradation of AR and CR which is confirmed by the dyes mineralized in λmax values. The catalytic process involved the electrons relay effect and is attributed with time. © 2017, Springer Science+Business Media New York.

Bio-Synthesis of Silver Nanoparticles Using Agroforestry Residue and Their Catalytic Degradation for Sustainable Waste Management

Methanolic extract of Cocos nucifera (C. nucifera) was collected using Soxhlet apparatus. C. nucifera methanolic extract was used to prepare Nickel nanoparticles (Ni NPs). Eco-friendly synthesized Ni NPs were confirmed by several analytical techniques such as UV–Visible spectroscopy (UV–Vis), Fourier Transform Infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-ray analysis (EDAX), Transmission Electron Microscope (TEM) and Zeta potential. The obtained results infer that green synthesized Ni NPs are in cubical shape with an average particle size of 47 nm. Synthesized Ni NPs were subjected to pesticidal activity against agricultural pest Callasobruchus maculates (C. maculates) which resulted in 97.31% mortality. These results were compared with commercially available standard Azadirachtin. Also we have studied larvicidal activity against Aedes ageypti (A. ageypti) larvae which resulted in LC 50 and LC 90 value of 259.24, 446.99 ppm respectively and the result proved to be significant which were processed by ANOVA LSD Tukey's test. © 2016 Elsevier B.V.

Nickel nanoparticles: a highly efficient and retrievable catalyst for the solventless Friedlander annulation of quinolines and their in silico molecular docking studies as histone deacetylase inhibitors

In recent years the utilization of secondary metabolites from plant extract has emerged as a novel technology for the synthesis of various nanoparticles. In this paper we studied the potential of nanocrystalline palladium nanoparticles production using acaricidal, insecticidal and larvicidal efficacy of Annona squamosa L aqueous peel extract as the biomaterial for the first time. The synthesized nanoparticles were characterized and confirmed as palladium nanoparticles by using UV-visible spectroscopy, XRD and TEM analysis. The results clearly showed that the compounds containing OH as a functional group played a critical role in capping the nanoparticles. Also the results highlight the possibility of green pathways to produce palladium nanoparticles. © 2011 Elsevier B.V.
