Abstract: Systems, devices, and methods for delivering a biological material into a cell are provided. In one example, a lance device for introducing biological material into a cell and configured for use in a nanoinjection system including a microscope is provided. Such a device can include a lance having a tip region and a shaft region, wherein the lance is structurally configured to allow entry and movement of the tip region into the cell along an elongate axis of the tip region and along a focal plane of the microscope. In another example, the lance can be configured to allow substantially horizontal entry and movement of the tip region into the cell.

Abstract: Systems, devices, and methods for delivering a biological material into an organelle of a cell are provided. In one aspect, for example, a method for introducing biological material into an organelle of a cell can include bringing into proximity outside of a cell a lance and a preselected biological material, charging the lance with a polarity and a charge sufficient to electrically associate the preselected biological material with a tip portion of the lance, and penetrating an outer portion of the cell with the lance and directing and inserting the lance into the cell but outside of the organelle. The method can further include discharging the lance to release at least a portion of the biological material, charging the lance with an opposite polarity and charge sufficient to electrophoretically drive at least a portion of the biological material into the organelle, and withdrawing the lance from the cell.

Abstract: Systems, devices, and methods for restraining a biological structure are provided. In one example, a biological structure restraining device can include a barrier structure, an opening defined in the barrier structure, and at least two contact points positioned adjacent to the opening and oriented to contact the biological structure, wherein the barrier structure and the opening are structurally positioned to receive the cell at the contact points. In another aspect, the device can also include a biological structure manipulator having a structure operable to press the biological structure against the contact points. In yet another aspect, the device can further include a biological structure injector having a structure operable to be inserted through the opening and into the biological structure, wherein the biological structure manipulator is operable to maintain the biological structure against the contact points as the biological structure injector is inserted into the biological structure.

Abstract: Systems, devices, and methods for protecting a biological material during delivery into a biological structure are provided. In one aspect, for example, a device for protecting and delivering a preselected biological material into a biological structure can include a lance operable to maintain a charge capable of associating a biological material thereto and at least one protective region formed on or in the lance, where the protective region protects the biological material during delivery into a biological structure.
