Influencing colloidal formation with optical traps

Ifat Jacob, Eitan Edri, Erel Lasnoy, Silvia Piperno and Hagay Shpaisman

We present a novel concept where optical traps are used to influence an ongoing polymerization process of emulsion droplets. By directed coalescence and partial fusion of intermediate nucleation sites, spherical and elongated colloids with specific dimensions are formed. The strength of this approach lies in its versatility and ease of making various changes to the end product without the need for chemical modifications.
