In comparison to the research on the experimental methods for these formulations and their application in various fields, the study of the interaction between drug and nanoparticle is less. In this study, we are reporting about the selection of metals for the formulation of nanocomposite with ferulic acid which is a well-known bioflavonoid having different medicinal activities. Ferulic acid contains only one –OH group which may reduce the conflict of selecting the metal atom binding site. For our study, we considered twelve metals which have been reported for having the potentiality to synthesis nanoparticles. These metals are gold, silver, copper, iron, zinc, nickel, platinum, palladium, rhodium, ruthenium, cadmium, and antimony. To mimic the actual nanocomposite structure, one metal atom has interacted with two molecules of ferulic acid. All nanocomposite model structures were designed using Avogadro software for windows. It was subjected to energy minimization and O-metal-O bond angle calculation. From the energy levels, it was observed that cadmium exhibited the lowest energy level and antimony showed the highest energy level suggesting their nanocomposite model structures as the most stable and unstable formulation respectively. </p> 2020-10-06T00:00:00+00:00 Copyright (c) 2020 Debraj Hazra, Rajat Pal https://journals.aijr.in/index.php/anr/article/view/2485 Green Synthesis of Silver Nanoparticles Using Waste Tea Leaves 2020-07-19T18:43:59+00:00 Darshana Rajput darshanaarajput@gmail.com Samrat Paul paulsamrat71@gmail.com Annika Gupta annikadurve@yahoo.com <p>Green synthesis of silver nanoparticles has gained momentum since the demand to synthesize nanoparticles in an eco-friendly way has increased significantly. Here we report, economic and cost-effective biosynthesis of silver nanoparticles using waste of tea leaves (<em>Camellia sinensis</em>). The aim of the study was to biosynthesize silver nanoparticles and to assess its potential applications such as antibacterial activity, plant growth induction and dye degradation. Standardization studies were done using UV- Spectroscopy to determine the optimum synthesis condition for synthesis of silver nanoparticles. The optimum conditions were found to be pH 6.0, ambient temperature condition and 5mM AgNO<sub>3</sub> concentration. Characterization studies using UV-Visible Spectroscopy, TEM and AFM analysis show nanoscale range of the particles. The silver nanoparticles showed maximum antibacterial activity against <em>K. pneumonia</em> followed by <em>E. coli</em> and minimum activity against <em>C. diptheriae</em>. The nanoparticles showed significant effect on the growth of <em>Vigna radiata</em> seeds at 50% concentration of nanoparticles. The particles immobilized on cotton cloth showed antibacterial activity against Gram positive organisms. Dye degradation studies showed that the nanoparticles are able to degrade phenol red and blue textile dye effectively.</p> 2020-07-05T00:00:00+00:00 Copyright (c) 2020 Darshana Rajput, Samrat Paul, Annika Gupta https://journals.aijr.in/index.php/anr/article/view/2717 Green Synthesis of Zinc Oxide Nanoparticles via Algal Route and its Action on Cancerous Cells and Pathogenic Microbes 2020-07-19T18:43:59+00:00 Priyankari Bhattacharya priyankari2004@yahoo.co.in Kasturi Chatterjee kasturichatterjee@gmail.com Snehasikta Swarnakar sikta@iicb.res.in Sathi Banerjee sathibanerjeeju@gmail.com <p>Application of metal oxide nanoparticles for treatment of melanoma cells and microbes is being investigated. Zinc oxide nanoparticles (ZnO NPs) deserve special mention where particles cause destruction of melanoma cells with minimal damage to healthy cells. In the present study, pure phase ZnO NPs with particle size of 3.1 nm were synthesized by green route using algal extract. Skin melanoma (B16F10) cells were treated with synthesized ZnO NP and compared with commercial ZnO NPs and analysed for ED50 for cellular viability using 3% (w/v) of the doses. Sensitivity of B16F10 cells towards green synthesized ZnO NP was found to be more than commercial ZnO NPs. Results showed greater reduction in viability of cells exposed to green synthesized ZnO NPs and with increasing dose of the ZnO NPs, percentage viability of cells gradually reduced. 50% decrease in cellular viability (ED50) was obtained for green synthesized ZnO NP at 3% dose while commercial ZnO exhibited ED50 at 6% of doses. The ZnO NP also showed antimicrobial activity against <em>Pseudomonas</em> sp. and <em>Staphylococcus</em> sp. Zone of inhibition (ZOI) exhibited by <em>Pseudomonas aeruginosa</em> and <em>Staphylococcus aureus</em> for disc diffusion and well diffusion assay was around 10-22 mm and 9-12mm respectively.</p> 2020-07-05T00:00:00+00:00 Copyright (c) 2020 Priyankari Bhattacharya, Kasturi Chatterjee, Snehasikta Swarnakar, Sathi Banerjee https://journals.aijr.in/index.php/anr/article/view/2806 Solubility of Mn in ZnO Crystallites Synthesized Using Solid State Techniques 2020-06-17T17:04:18+00:00 Esau Nii Abekah Akwetey Armah akweteyniiabekah@gmail.com Martin Egblewogbe megblewogbe@ug.edu.gh Hubert Azoda Koffi hakoffi@ug.edu.gh Alfred Ato Yankson ayankson@ug.edu.gh Francis Kofi Ampong kofiampong8@gmail.com Francis Boakye fboakye.sci@knust.edu.gh Josef Kwaku Ametefee Amuzu jkamuzu@ug.edu.gh Robert Kwame Nkum rknkum@gmail.com <p>Powder samples of Zn<sub>1-x</sub>Mn<sub>x</sub>O nanocrystal were synthesized at a temperature of 200 °C using solid phase method. Dopant concentrations of 0.005 ≤ x ≤ 0.5 were studied. Powder x-ray diffraction (PXRD) patterns of the samples were analyzed with a view of determining the onset of secondary phases, hence the solubility limit of the dopant. The solubility limit for Mn in ZnO samples synthesized at 200 °C is realized at x &lt; 0.3. With a regular pattern in increment of the Mn concentration, there were variations observed in the trend of the relative intensity, 2θ position and d-spacing indicating uneven addition of Mn (thus Mn<sup>2+</sup>, Mn<sup>3+</sup> or Mn<sup>4+</sup>).</p> 2020-09-30T00:00:00+00:00 Copyright (c) 2020 Esau Nii Abekah Akwetey Armah, Martin Egblewogbe, Hubert Azoda Koffi, Alfred Ato Yankson , Francis Kofi Ampong, Francis Boakye, Josef Kwaku Ametefee Amuzu, Robert Kwame Nkum
