    Abstract: Spraying apparatus and methods that employ multiple nozzle structures for producing multiple sprays of particles, e.g., nanoparticles, for various applications, e.g., pharmaceuticals, are provided. For example, an electrospray dispensing device may include a plurality of nozzle structures, wherein each nozzle structure is separated from adjacent nozzle structures by an internozzle distance. Sprays of particles are established from the nozzle structures by creating a nonuniform electrical field between the nozzle structures and an electrode electrically isolated therefrom.

    Abstract: A method for electrostatic spray-coating a medical device having a tubular wall, such as a stent, having an inner surface, an outer surface and openings therein. The tubular wall is grounded or electrically charged, and an electrically charged conductive core wire is located axially through the center of the stent. An electrical potential is applied to the conductive core wire to impart an electrical charge to the conductive core wire. The tubular wall is exposed to an electrically charged coating formulation, and the electrically charged coating formulation is deposited onto a portion of the tubular wall to form a coating. The electrical potentials of the conductive core wire and tubular wall can be repeatedly alternated.

    Abstract: A functional mammalian growth factor receptor/yeast histidine kinase chimera in Saccharomyces cerevisiae. In a preferred embodiment, the extracellular domain of the human epidermal growth factor receptor has been fused to the intracellular kinase domain of the SLN1 gene. The SLN1 gene encodes the plasma membrane sensor kinase of the yeast high osmolarity/glycerol response MAP kinase pathway. The chimeric protein is almost completely nonfunctional because the EGFR ECD is not capable of dimerization in the absence of ligand. In the presence of ligand, however, the chimeric kinase is activated and phosphorylation through the pathway is quantitatively repressed. This measure of pathway activity can be utilized to identify agonists and antagonists of the EGFR and other tyrosine kinase growth factor receptors in yeast cells.

    Abstract: A method of introducing biological material into cells includes providing one or more target cells and establishing a spray of substantially dispersed particles including biological material. The substantially dispersed particles have an electrical charge applied thereto such that one or,more of the substantially dispersed particles of the spray is introduced into one or more of the target cells. The spray of substantially dispersed particles may be established by dispensing a spray of microdroplets suspending particles. The electrical charge is concentrated on the suspended particles as the microdroplet evaporates. The suspended particles may include carrier particles with biological material or the suspended particles may be particles of biological material alone. The space charge effect of the concentrated electrical charge on the substantially dispersed particles of the spray enable one or more of the particles to be introduced into one or more of the target cells. An apparatus for introducing biological material into one or more target cells includes a biological material source including at least biological material and a dispensing device operably connected to the biological material source to receive biological material therefrom. The dispensing device provides a spray of substantially dispersed particles of at least the biological material with the spray of substantially dispersed particles having an electrical charge applied thereto.

    Abstract: An apparatus for electrostatically coating powder on a flat panel and a method for using such apparatus are provided. In the apparatus, a heating device is used to heat a panel to be coated and positioned on a powder spray chamber to a temperature of at least 100° C. and simultaneously charging the panel with a negative voltage of at least 20,000 volts. The high temperature and the high voltage of the otherwise non-conductive panel result in a panel that is electrostatically conductive. Powder particles that are charged with a high positive voltage are then injected toward the panel surface by an air pressure of at least 0.8 kg/cm2 until particles are adhered to the panel surface. The present invention novel method can be used advantageously at low costs due to its simple processing steps and as an environmentally friendly process since no solvent needs to be evaporated and released into the atmosphere. The present invention novel method further provides a low cost method for fabricating flat panel display devices due to its simplified processing steps.
