    Abstract: Disclosed is a method for selective electrofusion of at least two fusion partners having cell-like membranes and cellular or subcellular dimensions, comprising the following steps: A) the fusion partners are brought into contact with each other and B) an electrical field of a strength sufficient to obtain fusion and highly focused on the fusion partners is applied. The fusion partners are independently selected from the group consisting of a single cell, a liposome, a proteoliposome, a synthetic vesicle, an egg cell, an enucleated egg cell, a sperm cell at any development stage and a plant protoplast.

    Abstract: The present invention relates to the separation, quantitative measurement, and analysis of trace species using a combination of three steps in succession. First, trace species are separated from other species that are present. Second, the trace species are chemically modified to convert them into specific species that are advantageous for the third and final step. In this last step, cavity enhanced optical detection of the converted species is performed to detect and measure the concentrations of the species of interest. Because the last step has spectroscopic resolution, the concentration of isotopologues in each converted species can be determined. Further processing can provide the ratios between pairs of isotopologues, in particular the ratio of the rare isotopologues to the most abundant isotopologue.

    Abstract: A Bradbury-Nielson gate (BNG) includes a set of evenly spaced, co-planar, and parallel wires. The wires alternate in a repeating ABAB pattern, where all of the A wires are electrically connected to each other, all of the B wires are electrically connected to each other, and the set of A wires is electrically isolated from the set of B wires. Improved fabrication of Bradbury-Nielson gates is provided based on two key ideas. The first key idea is the use of wire positioning template surfaces having wire insertion features with enhanced spacing. Wire insertion features having enhanced spacing allow for non-microscopic assembly of finely spaced wire arrays. The second key idea is the use of two template surfaces, each having wires spaced by twice the eventual gate wire spacing. The use of two template surfaces facilitates making the alternating electrical contact required for a BNG.

    Abstract: Bradbury-Nielson gates for the modulation of beams of charged particles, particularly ion beams in mass spectrometry, have been produced with an adjustable wire spacing down to 0.075 mm or a smaller spacing. The gates are robust, they can be fabricated in less than 3 hours, and the method of production is reproducible. In time-of-flight mass spectrometers, fine wire spacing leads to improvements in mass resolution and modulation rates. Gates that were produced using this new method have been installed in a Hadamard transform time-of-flight mass spectrometer in order to demonstrate their utility.

    Abstract: An apparatus and method useful for sample injection in capillary electrophoresis is disclosed. The apparatus comprises an interface device with capillary and tubing inserted therein. Sample is injected through the tubing into the interface and is thereafter introduced into the capillary column in which the capillary electrophoresis separation is performed. The apparatus introduces precise amounts of sample into the capillary and the interface can be designed for split flow or direct sample introduction. Employing the interface device, the injection method permits samples to be introduced into capillaries without the need to disengage or to alter the electric field. The method is suited for adaptation with autosamplers or auto-injection systems.
