Objective

First trial of synthesizing PVA-Alginate beads with and without NaMT

Protocol

  1. Prepare an aqueous solution of 13% PVA and 0.02% sodium alginate at 60°C
    1. 1 gram of PVA and 0.16 g of sodium alginate in 7 mL of water (12.5% PVA and ~0.02% alginate)
    2. ~0.1 g of nanocomposites should be added to this mixture where applicable
  2. Cool dissolved and mixed solution to 35°C
  3. Prepare 210 mL of saturated citric acid with 2% calcium chloride
    1. Add 4.2 grams of calcium chloride to 210 mL of water
    2. Add citric acid to saturation
  4. Add the PVA-Alg-Nanocomposite mixture drop-wise to the gently stirring citric acid-calcium chloride solution using a thin needle
  5. Stir for 24hrs to allow solidification
  6. Rinse with water to remove excess reactants
