Phytogenic synthesis of nanoparticles from Rhizophora mangle and their bactericidal potential with DNA damage activity

Abstract

19The present study reports phytogenic synthesis of nanoparticles using aqueous extract of

Phytogenic synthesis of silver nanobactericides for anti-biofilm activity against human pathogen H. pylori

“…Similarly, the ratio of the metal salt: plant extract was also studied which showed 7:3 as optimal ratio to synthesize maximum nanobactericides. Similar findings have been well reported with plant mediated synthesis of nano-silver which reported the temperature dependent property for rapid synthesis [24]. Also, maximum absorbance at 424 nm has been reported which might be due to the phyto-reduction of metal salts.…”

“…The obtained results coincide with earlier scientific studies which provide the insight on the X-ray diffraction of plant mediated synthesis. For instance, according to study conducted by Syed et al [24] the diffraction pattern was measured between 10° and 80° at 2θ angle which displayed fcc structure of silver. The nanoparticles were synthesized from plant Chamerion angustifolium inhabiting Siberian region which displayed additional peaks due to bioorganic phase in plant extract.…”

“…Based on these considerations, the present study was designed and executed towards employing Acorus calamus L. to synthesize silver nanobactericides and their evaluation against clinically isolated H. pylori. Scientific studies report the effect of silver nanobactericides on wide range of microbial pathogens [23][24][25][26]. These properties can be highly valuable against treatment of drug resistant pathogens.…”

Phyto-mediated synthesis of zinc oxide nanoparticles using aqueous plant extract of Ocimum americanum and evaluation of its bioactivity

“…The solution was later centrifuged at 8000 rpm at room temperature (RT) for 15 min and the pellet was collected. The pellet obtained was subjected for repeated centrifugation thrice suspended with nanopure water, later air dried at RT for 2 h and preserved for further studies [36,37].…”

Bio-hybridization of nanobactericides with cellulose films for effective treatment against members of ESKAPE multi-drug-resistant pathogens

“…Plant materials were washed thoroughly under running tap water to remove the soil debris. The plant materials were chopped into small segments and 20 g of finely cut materials was added to one-liter beaker containing 500 ml of sterile distilled water (Syed et al, 2017a). The mixture was boiled for 30 minutes to obtained aqueous extract which was stored at 4 o C until further use.…”
