A monochloramine microelectrode with a tip size between 5 and 15 μm and using platinum wire was successfully designed, fabricated and characterized for in-situ monochloramine measurement within chloraminated distribution system biofilm. The monochloramine microelectrode showed sensitivity toward monochloramine concentrations (0.54 to 16.1 mg Cl2/L) at an applied potential of +550 mV (Ag/AgCl re...
Halothane, independent of oxygen tension, increased the signal of the gold/silver-silver chloride microelectrode. The output of microelectrodes at different oxygen tensions in the presence of increasing amounts of halothane has been measured. Halothane causes an increase in the electrode signal which is proportional to its concentration. This effect results from the polarographic reduction of h...
We have successfully operated enucleation of oocyte by using microelectric knife without any thermal collateral damage. Minimally-invasive cellular-scale ablation was achieved by the mono-dispersed microbubbles which were generated by a pulse discharge of microelectrode. The discharged output power and conductive area of microelectrode were controlled by glass shell insulation around the copper...
We have developed a hydrogel-based microstamp device that internally contains an electrochemical system for controlled supply of reactive ink to the stamp surface. An agarose stamp was combined with a microelectrode system for the controlled supply of HBrO by an electrochemical reaction. The supplied HBrO will detach the heparin layer pre-coated on substrates and allow selective adsorption of p...
We describe herein a method for the simultaneous measurement of temperature and electrochemical signal with a new type of thermocouple microelectrode. The thermocouple microelectrode can be used not only as a thermometer but also as a scanning electrochemical microscope (SECM) tip in the reaction between tip-generated bromine and a heated Cu sample. The influence of temperature on the SECM imag...
The fabrication and application of an intracellular K + -selective microelectrode is demonstrated. ZnO nanowires with a diameter of 100–180 nm and a length of approximately 1.5 μm are grown on a borosilicate glass microcapillary. The ZnO nanowires were coated by a K + -ionophore-containing membrane. The K + -selective microelectrode exhibited a K + -dependent potentiometric response versus an A...
