An electrophoretic display comprises a fluid and a plurality of nanoparticles having diameters substantially less the wavelengths of visible light such that, when the nanoparticles are in a dispersed state and uniformly dispersed throughout the fluid, the fluid presents a first optical characteristic, but when the nanoparticles are in an aggregated state in which they are gathered into aggregates substantially larger than the individual nanoparticles, the fluid presents a second optical characteristic different from the first optical characteristic. The electrophoretic display further comprises at least one electrode arranged to apply an electric field to the nanoparticle-containing fluid and thereby move the nanoparticles between their dispersed and aggregated states. Various compound particles comprising multiple nanoparticles, alone or in combination with larger objects, and processes for the preparation of such compound particles, are also described.

An emulsion is useful in allowing a wide variety of gene products to be expressed via eukaryotic in vitro expression. The emulsion comprises a silicone based surfactant, a hydrophobic phase and a hydrophilic phase; wherein the hydrophilic phase comprises a plurality of compartments containing a functional in vitro eukaryotic expression system.

The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

A process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner. A dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel such that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by the shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.

The present application relates to particles, compositions comprising such particles, and processes for making and using such particles and compositions. Such particles minimize or eliminate certain drawbacks of encapsulated benefit agents.When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed.

The present application relates to encapsulated benefit agents, compositions comprising such encapsulated benefit agents and processes for making and using compositions comprising such encapsulated benefit agents. Such encapsulated benefit agents eliminate or minimize one or more of the drawbacks of current encapsulated benefit agents and thus provide formulators with additional perfume delivery opportunities.
