“…CMEs were developed for the improvement of sensitivity, stability and selectivity in analytical applications using amperometric, voltammetric and potentiometric sensors. CMEs provide higher rates for the electrode reaction and show higher selectivity and sensitivity for determination of various compounds compared with ordinary electrodes …”

Two amino acids – d‐penicillamine (D‐PA) and tryptophan (TRP) – could be simultaneously determined in an aqueous solution (pH 7.0) using a novel benzoylferrocene‐modified carbon nanotube paste electrode. The results indicate that the electrode is efficient in terms of its electrocatalytic activity for the oxidation of D‐PA, leading to an overpotential reduction by more than 155 mV. Using square wave voltammetry, measurement of D‐PA and TRP in one mixture could be done independently from each other with a potential difference of about 205 mV. The proposed electrochemical sensor exhibited a linear calibration plot ranging from 1.0 × 10−6 to 8.0 × 10−4 m with a detection limit of 1.3 × 10−7 m for D‐PA. Finally, the proposed method was applied to the determination of D‐PA in a D‐PA capsule. Copyright © 2012 John Wiley & Sons, Ltd.

Over the last few decades, the development of several innovative hyphenated analytical techniques and their routine use in laboratories has led to new possibilities for the quantitative analysis of biomolecules. Today, the identification and quantification of biomolecules such as peptides and proteins are essential to answer important medical, pharmaceutical, and biological questions. To allow efficient detection and structure elucidation of biomolecules, several approaches including derivatization strategies were investigated and applied during recent years. This article summarizes the current approaches for labeling and presents the different types of organometallic derivatizing agents used as labels. Furthermore, their analytical potential with respect to quantification and structure elucidation for different applications in the field of bioanalysis is discussed.
