Leaf Extract for Nanoparticles Synthesis

Leaf Extract for Nanoparticles Synthesis
  1. CHECK LIST
    Leaves of desire tree/plant, Deionized Water, Beaek, Magnetic Stirrer with Temperature option, FIlter Paper
  2. STEP 1.
    Take fresh leaves of Bottle Brush or F. Panda. Wash properly and cut them into small pieces.
  3. STEP 2.
    Take Leaf pieces (25g) and mix with Deionized Water (100ml).
  4. STEP 3.
    Now boil the Leaves at around 80-90ÂșC for 5-10 minutes.
  5. STEP 4.
    When the water turns GREEN, filter it out and use it as reducing and capping agent for Nanoparticles synthesis.
  6. Factors Affecting Synthesis
    Species of Plant/Tree: Different types of Plants/Trees are having different types of chemical composition and concentration of specific chemical in its leaves. So different species of Plants/Trees can give the different particle size, size distribution. Even morphology can also be changed by using leaf extract of different plants/trees.
    Concentration of Leaves in Water: Concentration of leaves in water is very important for Nanoparticles synthesis. Higher concentration of leaves in water, leads to higher concentration of reducing and capping agent in water.
    Temperature: The temperature is another important factor in the synthesis of Nanoparticles, change in temperature leads to change in the particles size; also higher temperature leads to faster chemical Kinetics.
  7. NOTE: All the experiments should be done under the guidance of lab Incharge; and proper lab safety instructions.
