Figure 5From: Yucca-derived synthesis of gold nanomaterial and their catalytic potentialFractionation and separation of AuNPs. (A) Fractionation of AuNPs using sucrose density gradient centrifugation: F1-F4. (B) Separation of mostly spherical particles (a) from column fraction F1, large nanosheets (b) from fraction F2, and nanospheres: 10 to 30 nm (c, d) from fractions F3.Back to article page
