Green Synthesis of Gold Nanoparticles Using Moringa Oleifera Leaf Extract

Strategic Insights -

Scientists at the Universitas Negeri Surabaya have made a breakthrough in green synthesis, developing a new method to create gold nanoparticles using Moringa oleifera leaf extract. This innovative technique has the potential to revolutionize the field of nanotechnology, providing a sustainable and environmentally friendly alternative to traditional methods. The research team, led by Ratna Indriyani, has successfully synthesized gold nanoparticles with a concentration of 20 ppm, which exhibited antioxidant activity and suppressed free radicals by up to 83%.

Key Takeaways:

  • The research team used a bottom-up approach with a green synthesis method to synthesize gold nanoparticles with a concentration of 20 ppm.
  • The gold nanoparticles were characterized using a UV-Vis spectrophotometer, which showed a maximum wavelength shift from 309 nm to 542.80 nm after synthesis with Moringa oleifera leaf extract.
  • The TEM results showed a diverse cluster size of gold nanoparticles with an average length of 6.635 nm and still in the nanometer size range.
  • The antioxidant activity test of gold nanoparticles obtained a percent of free radical suppression sequentially of 69, 77, 76, and 83% at concentrations of 2.5, 5, 10, and 20 ppm.
  • The IC50 value of gold nanoparticles was not provided in the study.
  • The research study was published in the Jurnal Pijar MIPA (Pengkajian Ilmu dan Pengajaran Matematika dan Ilmu Pengetahuan Alam) in 2024.
  • The study was conducted at the Departement of Chemistry, Faculty of Mathematic and Natural Science, Universitas Negeri Surabaya.

Statistics:

  • 20 ppm concentration of gold nanoparticles used in the synthesis.
  • 69, 77, 76, and 83% percent of free radical suppression obtained at concentrations of 2.5, 5, 10, and 20 ppm.
  • 309 nm to 542.80 nm wavelength shift after synthesis with Moringa oleifera leaf extract.
  • 6.635 nm average length of gold nanoparticles.
  • 4-5 nm highest frequency size of gold nanoparticles.
