SMALL CLUSTERS OF ENCAPSULATED POLYMER MICROSPHERES
It is possible to synthesize and separate bulk quantities of colloidal
clusters composed of polymer microspheres. Clusters containing two to fifteen
particles are isolated using density gradient centrifugation. The clusters can
then be encapsulated in oil droplets and the droplet size is controllable. We
are currently investigating methods to increase the yield and purity of clusters
containing two to four particles. We are also studying the effectiveness of
various solvents for encapsulating the clusters and assembling the encapsulated
clusters into monolayers.
