Various particle transport systems and components for use in such systems are described. The systems utilize one or more traveling wave grids to selectively transport, distribute, separate, or mix different populations of particles. Numerous systems configured for use in two dimensional and three dimensional particle transport are described.

Systems and methods for transporting particles

An improved method and apparatus for delivering medication to the lungs is described. Acoustic ink printing technology is modified to operate as an inhaler that generates tiny droplets near a patient's nose or mouth. The tiny droplets are easily carried by air currents into the patient's lungs. The inhaler itself is preferably a battery operated portable device that can be easily carried and easily cleaned to avoid contaminating the medication.

Inhaler that uses focused acoustic waves to deliver a pharmaceutical product

A method of using electrokinetics for separating particles in a buffer solution is provided, where a chromatographic column is provided having a non-uniform internal longitudinal cross-section. At least one main inlet for inputting solution and at least one main outlet for outputting solution are provided. At least one sample inlet and at least one sample outlet are provided. The particle is introduced to the column from the sample inlet and fractionated samples are eluted from the sample outlet, where quality control and further analysis are enabled. An electric field is applied to the solution in the column to generate a charged double layer at a solid-liquid interface within the column. The electric filed moves ions within the double layer, and a non-uniform velocity profile is induced to the buffer solution. The moving ions carry the particles along the column and the particles are separated according to size or charge.

Method of separation of polymers

A method of making a multichromal sphere includes the steps of preparing a composition of at least (1) a matrix material and (2) at least two sets of particles, each of the sets of particles having a color different from at least one of another of the sets of particles and a segregation (e.g., an electrical or magnetic) property different from at least one of another of the sets of particles, encapsulating the composition within a shell to form an encapsulated sphere, immobilizing the encapsulated sphere in a manner to restrict at least rotation of the encapsulated sphere, subjecting the immobilized encapsulated sphere to an external field associated with the segregation property different among the sets of particles, under conditions in which the sets of particles are able to migrate within the matrix material, thereby producing color segregation in the immobilized encapsulated sphere, and solidifying the matrix material while substantially maintaining the color segregation. In the multichromal spheres, each of the sets of particles is segregated within a separate segment of the solidified matrix material of the core on the basis of the different segregation property.

Method of using focused acoustic waves to deliver a pharmaceutical product

A reflective display device includes a flexible pouch of ordered copolymer layers with a lamellar structure and a solvent, the flexible pouch having at least a first and second surface. A substrate is placed in operative contact with a first surface of the flexible pouch. Thereafter, one of a pressure or heat application mechanism is placed in operative connection with at least one of the first and second surfaces of the flexible pouch. A controller operatively associated with one of the pressure or heat application mechanisms, is used to selectively apply pressure and/or heat to the flexible pouch. The application of the heat or pressure at a specific location on the flexible pouch results in a change of reflectivity in the ordered copolymer layers, thereby altering the color at that location.

Flexible micron-thin display device

A display medium including a plurality of electrically photosensitive particles positioned within at least one ambipolar shell to form at least one first composite particle, and a plurality of white particles encapsulated in a plurality of insulating shells to form a plurality of second composite particles. A photoelectrophoretic display and method of photoelectrophoretic imaging are also disclosed.

Color-enabled electrophoretic display and medium

The present invention comprises an electromagnetophoretic ink material for use as electronic and magnetic display elements. In particular, the present invention relates to the preparation and use of microencapsulated aspect elements having both an electrostatic layer and a magnetic layer, and that can be addressed to produce a display aspect by the application of external electric fields and external magnetic fields.

Electromagnetophoretic display system and method

Provided is a priming mechanism for priming a biofluid drop ejection device having a drop ejection opening leading to an ejection reservoir. The priming mechanism includes a vacuum unit which generates a vacuum force, connected to a vacuum nozzle. The vacuum nozzle is located over the drop ejection opening. A disposable sleeve or tubing is attached to the vacuum nozzle and is placed in operational contact with the drop ejection opening. A fluid height detection sensor is positioned to sense a fluid height within at least one of the disposable tubing and the vacuum nozzle. Upon sensing a predetermined fluid height, by the fluid height detection sensor, the priming operation is completed, and the primer mechanism is removed from the operational contact with the drop ejection opening.

Priming mechanisms for drop ejection devices

An improved method for the sequencing of DNA fragments is provided. The method includes using a known process for DNA fragment separation, such as capillary electrophoresis, and imaging the resultant gel plate with a full-width array scanner or a two-dimensional amorphous silicon image sensor array. The DNA sample is placed within a well of the separation apparatus, such as a capillary tube or plurality thereof. The separation apparatus is then placed in a buffer. An electric field is then applied, forming a bias between the ends along which the sample is separated. Once separated, the large area detector scans the entire gel plate and resultant image data is provided. By way of the improved method, the entire gel plate can be scanned at the same time and repeatedly, resulting in greater accuracy and a shorter time to sequence.

Imager for DNA sequencer

A particulate dispensing device includes a housing having a wall at least partially forming a housing cavity. A dispersive element and a particulate filter are each supported in the housing cavity in spaced relation to one another forming a fluidizing chamber. A dispensing tube extends from the fluidizing chamber for dispensing fluidized particulates or aerosol from the device. The particulate dispensing device generates the fluidized particulates or aerosol from a particulate bed within the fluidizing chamber, and dispense the particulates through the dispensing tube to a downstream delivery site. One or more dispensing devices can be used in a system to deliver the fluidized particulate matter to the delivery site. In one system a delivery line from an associated dispensing device directly delivers particulate matter to the delivery site. In another system, each delivery line of one or more dispensing devices delivers particulate matter to an associated delivery member that includes a longitudinally extending channel having an exit orifice. A propellant source is in fluid communication with a propellant port in the channel, and provides propellant flow along the channel. The dispensing lines deliver the fluidized particulate matter or aerosol into the propellant flow. The delivery site is supported adjacent the exit orifice such that the propellant flow and particulate matter therein are delivered to the delivery site.
