  • The method adopted is entirely a green chemistry approach and is facile, economical, and efficient in mass production. (ajgreenchem.com)
  • Contrary to popular belief, "green" does not relate to the colour green, but rather to the process of making nanoparticles out of metal salts by using the reducing property of biologically active compounds [16,17]. (ac.ir)
  • 9]. Synthesis of Ag NPs was performed at the biochemistry laboratory of the Biomedical Engineering Department at the University of Technology in Iraq. (ac.ir)
  • The antibacterial activity was assessed against E. coli and S. aureus microbes and results revealed that the silver nanoparticles are highly active against the selected microbes and silver nanoparticles have potential for application in biomedical field. (bosaljournals.com)
  • Cyanobacteria-mediated silver nanoparticles synthesis approach has proven to be more efficient and eco-friendly in achieving biomedical applications compared to physical and chemical prototypes. (japsonline.com)
  • These higher doses are based on the amount of blood in the body, the amount of silver that has proven to kill pathogens, and the amount of silver absorbed through oral intake. (earthclinic.com)
  • An in situ method has been developed to fabricate gold nanoparticle (Au NP) films on different substrates, regardless of whether they are hydrophilic or hydrophobic surfaces, including glass, 96-well polystyrene plates, and polydimethylsiloxane (PDMS). (nature.com)
  • Another important finding is that the nanoparticles which are hydrophilic, hydrophobic or both can be effectively prepared by regulating the reflux time in this method. (ncl.edu.tw)
  • In place of harmful physical and chemical processes, green synthesis provides a viable alternative [13-15]. (ac.ir)
