Objective
ProcedureAdding Variables to 30:1 Lysozyme-AuNP Synthesized 3/26/141. Add 2.25 mL of each variable to 4.5 mL of sample.
2. Put one of each sample in the following three environments: 4°C, 24°C, 36°C. Conductivity Measurements of 30:1 Lysozyme-AuNP at Room Temperature
Atomic Absorption PreparationCreating the Gold Stock Solutions
Atomic Absorption Samples Solutions with the following Au:lysozyme ratio at room temperature were run on the AA:
