Silver nanowire has potential applications on transparent conducting film and electrode of electrochemical capacitor due to its excellent conductivity. Transparent conducting film (G-film) was prepared by coating silver nanowires on glass substrate using Meyer rod method, which exhibited better performance than carbon nanotube and graphene. The conductivity of G-film can be improved by increasing sintering temperature. Electrode of electrochemical capacitor (I-film) was fabricated through the same method with G-film on indium tin oxide (ITO). CV curves of I-film under different scanning rates had obvious redox peaks, which indicated that I-film exhibited excellent electrochemical pseudocapacitance performance and good reversibility during charge/discharge process. In addition, the specific capacitance of I-film was measured by galvanostatic charge/discharge experiments, indicating that I-film exhibits high special capacitance and excellent electrochemical stability.

We describe a novel temperature-controlled perfusion apparatus for electrophysiological studies on isolated cells or membrane patches. The apparatus uses a transparent conducting film of indium-tin-oxide as a heating element. The film heater deposited on a glass sheet allows us to construct a structurally simple apparatus that is able not only to heat directly the bath chamber but also to preheat the perfusion solution on the stage of an inverted microscope. The structure ensures a uniform temperature in a bath chamber that has a working area of approximately 6 X 12 mm2 and a capacity of 1 ml. A control unit, designed for operation of the apparatus, regulates the temperature of the bathing solution without introducing electrical noise in a range from ambient temperature to greater than 37 degrees C with an accuracy within +/- 1 degree C. The apparatus is 12 mm in height and designed to fit on the stage of a standard inverted microscope. Since the bath chamber for perfusion experiments is readily interchanged with others, the apparatus can be used widely in microscopic studies of various cells in static solutions.

Transparent conducting electrodes (TCEs) formed with silver nanowires (AgNWs) have attracted attention as substitutes for indium tin oxide (ITO). However, the randomly deposited AgNW film performs poorly in terms of the transmittance and sheet resistance to serve as a substitute of ITO. To improve the performance of the AgNW film, we fabricated a grid-patterned AgNW by modifying the surface energy of the substrate. The hydrophobized surface was selectively etched by UV light through a quartz chrome mask, and a suspension of AgNWs in isopropyl alcohol/ethylene glycol mixture was coated on the substrate by a meniscus dragging deposition process. The grid-patterned AgNW film has a lower percolation threshold and a 13% higher figure-of-merit value compared to the randomly deposited AgNW film. The transparent thin films with a grid structure of AgNWs exhibit the high electrical conductivity with a sheet resistance of 33 Ohm/sq at a transmittance of 92.7% (λ = 550 nm).
