The present invention relates to amphiphilic polymers, and micelles and compositions comprising the same, and their use in a variety of biological settings, including imaging, targeting drugs, or a combination thereof for diagnostic and therapeutic purposes. When print data is obtained, the setting device displays a preview of a print page image represented by the print data. A thermal-capillary pump can be operative with the electrodes and an ion exchange electrolyte, and operatively connected to the fuel processor.
