Reagents for use in preparing a therapeutic liposome composition sensitized to a target cell are described. The user interface is provided with a plurality of modes of user operation, including an installment mode which allows the user to configure the user interface to perform in a desired manner while the element is being installed. The coupling device may include a bushing insertable and positionable within one of the mating bore holes, and a pin insertable and positionable within the bushing and the other of the mating bore holes. The integrated transponder chip is designed for a near-field application and is intended to be active in a range of a few centimeters. The regulation process may boost battery voltage allowing the use of a more compact, low-voltage batteries. The epitaxial printing process of the present invention utilizing epitaxial growth, wafer bonding and a recrystallization anneal.
