Silver Nano Particles - Methods
A ---- ml aliquot of the silver binding peptide ( sequence -----) was obtained from.... Two different experiments were setup using the following protocols.
Protocol 1:
A protocol that was initially used to identify metal binding peptides by was used to nucleate and grow silver nanoparticles[1].
- 120 ul peptide (8ug/ul)
- 14 ul HEPES buffer at pH 7.5
- 1.4 ul AgNO3 at 20mM
- 4.6 ul H2O
The solutions were mixed and incubated at room temperature for 24-48 hrs.
Protocol 2:
A method designed by Fromm and Wennemers [2] was used to form silver nanoparticles by using a chemical reducing agent, sodium ascorbate (NaAsc.)
- 120 ul peptide (8ug/ul)
- 14 ul NaAsc. at 2mM
- 1.4 ul AgNO3 at 20mM
- 4.6 ul H2O
