Electrochemical Detection of Single Molecules
Accounts of Chemical Research, 1995The electrochemical behavior of a single molecule can be observed by trapping a small volume of a dilute solution of the electroactive species between an ultramicroelectrode tip with a diameter of ∼15 nanometers and a conductive substrate. A scanning electrochemical microscope was used to adjust the tip-substrate distance (∼10 nanometers),

Electrochemical aptasensor for tetracycline detection
Bioprocess and Biosystems Engineering, 2009An electrochemical aptasensor was developed for the detection of tetracycline using ssDNA aptamer that selectively binds to tetracycline as recognition element. The aptamer was highly selective for tetracycline which distinguishes minor structural changes on other tetracycline derivatives.

Electrochemical detection in capillary electrophoresis
ELECTROPHORESIS, 1997AbstractRecent advances in the design and application of electrochemical detection (EC) systems in capillary electrophoresis (CE) are reviewed, with the objective of providing the non‐electrochemist with a state‐of‐the‐art picture of CEEC instrumentation and an overview of the primary analytes and samples for which the technique is best suited.

Electrochemical Approach To Detect Apoptosis
Analytical Chemistry, 2008This paper reports an electrochemical approach for detection of apoptosis. Here we prepare a gold electrode modified with a helix peptide ferrocene (Fc)-GDGDEVDGC. Fc is used as an electroactive reporter and the peptide as a recognition and cleavage site of caspase-3, which is a special proteinase to apoptosis.

Tape-Stripping Electrochemical Detection of Melanoma
Analytical Chemistry, 2019A noninvasive electrochemical melanoma detection approach based on using adhesive tapes for collecting and fixing cells from a suspicious skin area and transferring the cells into a scanning electrochemical microscope (SECM) is presented. The adhesive layer collects the cells reproducibly and keeps them well adhered on the tape during experiments in an

Detection Limits and Selectivity in Electrochemical Detectors
Analytical Chemistry, 1988Electrochemistry provides a powerful set of tools for analysis. Its power derives from the fact that electrochemistry is inherently chemical in nature. This instrumentation article describes developments in current-carrying electrochemical detectors.

Electrochemical Detection of Nanoparticles
2015The electroanalysis of nanoparticles is summarised in a review with 172 references. A brief overview of nanoparticle properties is followed by a critical survey of the state-of-the-art methods for nanoparticle detection. The merits of electrochemistry based techniques are discussed and developed in the context of stripping voltammetry and the recently ...
