Ionic Strength Effects on Fibers	Main project page Previous entry      Next entry
Objective To determine the ionic strength of 50 mM tris buffer (pH 10.1) on AuNP fibers. Description Centrifuge fiber solution made on 03/27/12 at 4500 rpm for 45 minutes. Remove solution, leaving only supernatant. Add 5 mL 50 mM tris (pH 10.1). Centrifuge for 10 min at 13200 rpm. Take UV-vis data. Data Graph of absorbance vs wavelength for tris buffer added to AuNP fibers: Notes
