    摘要: A method is provided to disrupt tau entanglements and amyloid plaques in a person's brain. An ultrasound profile generated by an ultrasound device is applied to the person's brain. The generated ultrasound profile is characterized by a frequency between 20-100 kHz, a pulse power greater than 10 W/cm−2, a pulse length greater than 1 microsecond, and an interval between pulses greater than 1 millisecond. The method is performed without intravenous injection of microbubbles to the person or use of preformed microbubbles.

    摘要: 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.

    摘要: Fluid ejection using multiple voltage pulses and removable well modules is provided. Ejection of an electrically conductive fluid is accomplished by the application of two or more high voltage pulses. The high voltage pulses are applied across a conducting nozzle for transporting the fluid and a grounded conducting ring positioned below the nozzle. Ejected fluid droplets fall through the center of the conducting ring and onto a substrate. The presence and approximate size of the ejected droplets can be sensed and used for feedback for the high voltage pulses. The conductive fluids are stored in well modules that are not permanently attached to a well plate. Each removable well module includes a conducting nozzle and can include valves and a memory chip. Control circuits are also provided to independently control the high voltage pulses applied to the individual well modules.

    摘要: The present invention provides an artificial corneal implant having an optically clear central core and a porous, hydrophilic, biocompatible skirt peripheral to the central core. In one embodiment, the central core is made of an interpenetrating double network hydrogel and the skirt is made of poly(2-hydroxyethyl acrylate) (PHEA). In another embodiment, both the central core and the skirt are made of interpenetrating double network hydrogels. The artificial corneal implant may also have an interdiffusion zone in which the skirt component is interpenetrated with the core component, or vice versa. In a preferred embodiment, biomolecules are linked to the skirt, central core or both. These biomolecules may be any type of biomolecule, but are preferably biomolecules that support epithelial and/or fibroblast cell survival and growth. Preferably, the biomolecules are linked in a spatially selective manner. The present invention also provides a method of making an artificial corneal implant using photolithography.
