Objective

All of the reaction mixtures from Wednesday's lab produced a homogeneous solution of nanoparticles (AuNPs) instead of fibers (AuNP fibers).

The most likely reason is that the balance did not properly record the mass of the lysozyme. Today I am going to remake the lysozyme solution and synthesize several 1 mL samples of AuNP fibers.

Description

Lysozyme stock solution

  1. Mass of lysozyme = 15.21 mg
  2. Molar mass of lysozyme = 14307 g/mol
  3. volume used = 50.0 mL
  4. Lysozyme concentration = 21.3 μM

For these samples, I am using the gold stock solution from Wednesday and HPLC-grade water.

Trial solutions to determine if the stock is good

  1. Au:Lysozyme ratio = 45
    1. Volume of Au stock = 422 μL
    2. Volume of Lysozyme stock = 1,297 μL
    3. Volume of Water = 3,281 μL
    4. Place in a test tube and cap with foil
  2. Au:Lysozyme ratio = 50
    1. Volume of Au stock = 422 μL
    2. Volume of Lysozyme stock = 1,167 μL
    3. Volume of Water = 3,411 μL
    4. Place in a test tube and cap with foil
  3. Au:Lysozyme ratio = 55
    1. Volume of Au stock = 422 μL
    2. Volume of Lysozyme stock = 1,061 μL
    3. Volume of Water = 3,517 μL
    4. Place in a test tube and cap with foil
  4. Au:Lysozyme ratio = 60
    1. Volume of Au stock = 422 μL
    2. Volume of Lysozyme stock = 972 μL
    3. Volume of Water = 3,605 μL
    4. Place in a test tube and cap with foil
  5. Au:Lysozyme ratio = 65
    1. Volume of Au stock = 422 μL
    2. Volume of Lysozyme stock = 898 μL
    3. Volume of Water = 3,680 μL
    4. Place in a test tube and cap with foil
  6. Au:Lysozyme ratio = 70
    1. Volume of Au stock = 422 μL
    2. Volume of Lysozyme stock = 834 μL
    3. Volume of Water = 3,744 μL
    4. Place in a test tube and cap with foil

Samples for Students (1 mL in eppendorf tubes)

  1. Au:Lysozyme ratio = 45
    1. Volume of Au stock = 84 μL
    2. Volume of Lysozyme stock = 259 μL
    3. Volume of Water = 656 μL
    4. Place in a test tube and cap with foil
