Abstract
There is provided a method for synthesizing colloidal nanoparticles comprising the step of creating a reactive three-phase foam containing reactants therein for synthesizing the colloidal nanoparticles.
Claims17
A method for synthesizing colloidal nanoparticles via making a reactive three-phase foam, wherein the method comprises:
- injecting at least two fluids into a microchamber, wherein one or more of said at least two fluids is immiscible with one or more of the other of said at least two fluids;
- mixing said at least two fluids that are immiscible with each other to form a two-phase fluid flow wherein one phase of said two-phase fluid comprises seeded nanoparticles and reactants;
- pinching off said at least two fluids at a junction in said microchamber, said junction being in fluid communication with a continuous phase conduit, to alternate the at least two phases flowing into said conduit;
- and
- coating said two-phase fluid flow with a continuous phase to form a three-phase foam for synthesizing said colloidal nanoparticles from said reactants and said seeded nanoparticles.
