In this overview we explore the electroanalytical sensing of important chemical reagent hydrazine, highlighting plethora electrochemical strategies utilised from first reports in 1951 to present day.

Several new books and journals containing material of electroanalytical and electrochemical interest have appeared. The newest edition of “Standard Methods of Chemical Analysis” (329) includes chapters discussing the fundamentals of electrogravimetric and coulometric methods. Zozulya has written a brief monograph on coulometric analysis (341) and coulometric titrations in nonaqueous solvents ha...

In this overview, we explore the electroanalytical determination of theophylline. Theophylline finds use as a bronchodilator for treating diseases such asthma and chronic obstructive pulmonary disease (COPD). There is need to measure concentration theophylline in pharmaceuticals QA/QC purposes well plasma samples ensure doses are at correct therapeutic levels. If levels deviate from (10–20 µg/m...

Two new methods of electroanalysis are described. These methods are based on membranes containing monodisperse Au nanotubules with inside diameters approaching molecular dimensions. In one method, the analyte species is detected by measuring the change in trans-membrane current when the analyte is added to the nanotubule-based cell. The second method entails the use of a concentration cell base...

Screen-printed back-to-back microband electroanalytical sensors are applied to the quantification of lead(II) ions for the first time. In this configuration the electrodes are positioned back-to-back with a common electrical connection to the two working electrodes with the counter and reference electrodes for each connected in the same manner as a normal "traditional" screen-printed sensor. Pr...

We present the electroanalytical sensing of atropine using disposable and economic screen printed graphite sensors. The electroanalytical determination of atropine is found to be possible over the concentration range of 5 μM to 50 μM with a detection limit of 3.9 μM (based on 3-sigma) found to be possible. We demonstrate proof-of-concept that this approach provides a rapid and inexpensive sensi...
