Separation of Nanoparticles in a Density Gradient: FeCoC and Gold
By varying the step gradient densities and centrifuge exposure time, this method could be used for separation of nanoparticles of a larger size range, which was demonstrated by (on average) 7 nm FeCoC NP separation (see TEM images of initial 7 nm FeCoC NPs in the Supporting Information). A gradient of higher density steps (20+30+

A practical proposal for silver nanoparticles (Ag
example, considering a centrifuge with the parameters (maximum speed = 12,000 rpm, rotor radius = cm, and maximum separation capacity of 15 nm) in an approximate way, we could determine the probable size of the nanoparticles that we could separate between 8000 and 10,000 rpm, which would be between 30 and 40 nm.

First, 400 L of neutral PBS buffer was added into the centrifuge tube, and then a certain amount of 100 L Pd 1 Cu 7 alloy NPs (most active composition) was added. In colorimetric detection mode, 100 L of TMB (10 mM) was added to the test system. After that, H 2 O 2 solution with the concentration of 4 mM to 14 mM was prepared with the serially diluted

Gold Nanoparticles – nanoComposix
Gold Nanoparticle Concentration. Gold nanoparticles are provided in two concentrations, NanoXact ( mg/mL) and BioPure (1 mg/mL). At NanoXact concentrations, the gold particles are a ruby red or yellow/red color in solution depending on their size. The BioPure formulation is 20X more concentrated and is red or red/yellow and opaque.

What You Need to Know About Centrifuges and Centrifugation
It''s All About Balance. Centrifugation produces centrifugal forces to effectively separate sample components based on size and density. Small weight imbalances can cause abnormal vibrations that can damage the rotor. An unbalanced centrifuge is as dangerous as an unstable chemical reaction.
