| Swarming process: Gold microparticles can be organized into discrete regions by using an electrolyte gradient triggered by adding hydrazine to hydrogen peroxide (see picture). Control of the surface chemistry and particle density is used for tailoring the size and shape of the microparticle swarms. |
Today I was acknowledged in a paper entitled "Chemically Triggered Swarming of Gold Microparticles" by Kagan et al. in Anglewante Chemie. If you have a subscription to this Journal then you can view it
