  • Patent number: 7393680
    Abstract: Disclosed is a method for penetration of lipid bilayer membranes in order to insert at the tip of a hollow needle-shaped object, such as a micropipet-, into a container formed of a lipid bilayer membrane, wherein said container is placed between said needle-shaped object, with the tip of said needle-shaped object placed in contact with said conainer in such a way that it applies a mechanical force to the lipid membrane of said container, thus mechanically straining it, and a second electrode, whereupon a transient electric pulse of 1-to-103 V/cm is applied between the electrodes, resulting in a focused electrical field over said container C which induces a dielectric breakdown of the lipid bilayer causing the needle-shaped object to penetrate the container. Disclosed is also an electroinjection method based on the above method, wherein substances are introduced through the needle-shaped object and into the container after penetration of the needle-shaped object.

  • Patent number: 7109034
    Abstract: The invention relates to a method for permeabilization of a cell structure consisting of a single cell, an intracellular structure or an organelle comprising the following steps: (a) microelectrodes, preferably two carbon fiber electrodes or hollow fiber electrodes, are provided, (b) the microelectrodes are connected to a power supply, (c) the electrodes, individually controlled by high-graduation micromanipulators, are placed close to the cell structure at an appropriate inter-electrode distance, and (d) a highly focused electric field of a strength sufficient to obtain electroporation is applied between the electrodes. The method may be used in order to transfer cell impermeant solutes, such as drugs or genes, into the cell structure or out of the cell structure, in biosensors, in the treatment of tumours and neurodegenerative diseases and in the study of biophysical processes.

  • Publication number: 20050217750
    Abstract: A method and apparatus for treating a fluid. A method for treating a fluid may include combining two or more separate streams into a common stream and then splitting the common stream into a new set of separate streams wherein the separate streams may possess different properties. The separate streams may be combined to produce a gradient, such as a concentration gradient or shear gradient. The apparatus of the invention may provide a network of fluidic channels that may be used to manipulate a fluid to produce, for example, a gradient or a series of solutions containing a substance at varying concentrations.

  • Publication number: 20050003411
    Abstract: Embodiments of the present invention employ complexly shaped, high-surface-area channels for separation and purification of molecules, including important biopolymers such as proteins, glycoproteins, polysaccharides, and other molecular components of living cells. The relatively large internal surface areas of the complexly shaped channels employed in embodiments of the present invention provide, in comparison to traditional, simply shaped separation channels, increased heat dissipation during electrokinetic separation, and a decreased tendency for bulk-solution flow. Heat dissipation prevents high temperatures that can denature proteins and that can induce thermal currents within the separation channel. Bulk-solution flow within a separation channel can overwhelm the generally linear, electrical-potential-induced migration of molecules that leads to efficient and well-resolved molecular separations.
