    Abstract: The invention involves methods and apparata for manipulating micro-/nanoobjects. A holder exerts a weak attractive force on the micro-/nanoobject (by, for example, suction from negative fluid pressure, electrostatic attraction, magnetic attraction, etc.). A vibrator coupled to the holder generates orbital motion in the holder in at least one plane. As long as the attractive force is not too high, the orbital motion of the holder will cause rotation of the micro-/nanoobject, with the attractive force of the holder maintaining the micro-/nanoobject adjacent the holder during such rotation. Once the micro-/nanoobject has been rotated to a desired orientation, the attractive force of the holder on the micro-/nanoobject can be increased to such a level that the micro-/nanoobject will be firmly fixed to the holder. The orbital motion of the holder can be provided in conjunction with translational motion of the holder (as provided by a microdrive or similar positioning device), thereby allowing positioning of the micro-/nanoobject in as many as six degrees of freedom.

    Abstract: A microtool mount includes an elongated finger terminating in a tip. The finger has a pair of valley edges from which valley walls descend to terminate in a valley floor, thereby defining a valley between the valley walls and floor. The valley extends from the tip along a path parallel to at least a portion of the length of the finger. A microcapillary or other rodlike microtool may be accommodated within the valley, and a fastening member, preferably a magnet, may be removably affixed to the finger above the valley to maintain the microtool within the valley. The valley edges are preferably planar along at least a portion of the length of the finger so as to allow the magnet to more firmly affix to the finger.

    Abstract: An electroporation chamber is provided wherein cells are borne by a fluid medium through a conductive mesh receiving electrode (with the mesh size being such that it allows passage of cells of the desired size/type) and into the chamber. The cells are then captured on a conductive mesh capturing electrode having a mesh size which retains the desired cells. The electrodes are then charged to effect electroporation or other operations within the captured cells between the electrodes. If desired, different fluid media may flow through the electrodes and chamber (and over the cells) during such activities. When operations are completed, fluid flow may be reversed to carry the treated cells back out of the chamber through the receiving electrode.
