    摘要: A dispenser and methods for transferring liquids are disclosed. The dispenser may include a capillary tube with tip having an aperture, a piezoelectric actuator coupled to the capillary tube at a location. Actuation of the piezoelectric actuator causes a pressure wave to propagate along the capillary tube toward the tip such that radial motion at the location is transmitted as distally extending axial motion of the tip, thereby causing a droplet of a predetermined volume to be ejected from the aperture. In some embodiments, the capillary tube has a modulus of elasticity in a range which dampens acoustical noise from the actuation and provides single drop stability over a range of drop sizes.

    摘要: Methods and techniques for controlled printing of a cell sample for karyotyping are provided. The methods can involve matrix printing using on-the-fly printing or dispensing to accurately spread cells within at least one cell sample on a surface in preparation for karyotyping, and further analysis. Advantageously, the methods result in a uniform distribution of chromosomes of the cell suspension or sample on the surface of a substrate which can be substantially discretely identified, and also provide for efficiency in a subsequent staining process and any further analysis of the stained chromosomes using a microscope or other imaging device.

    摘要: Systems, devices and methods are provided, for acquiring and dispensing predetermined volumes of liquids and, in particular, to a unique piezoelectric dispenser for acquiring and dispensing of small volumes of fluid in an automatic or manual production of DNA arrays and assays, wherein droplets are dispensed in a single drop format with volumes that may range from about a few picoliters to several nanoliters. The dispenser can advantageously utilize a disposable capillary tube assembly while desirably retaining the piezoelectric actuator for subsequent further uses, thereby mitigating the possibility of cross contamination of fluids and providing an economical and cost effective approach with reuse of the piezoelectric actuator for further operation such as with a variety of liquids to be dispensed and transferred. A unique longitudinal transducer can transmit radial tube displacement into controlled axial motion of the tube.
