Ferrocene-modified DNA probes formed fully matched duplexes and bulge-containing ones with wild-type and insertion/deletion-type complements of clinical importance, respectively. Cyclic voltammetry measurements revealed that the bulge-containing duplexes showed an increased flexibility compared to the fully matched duplexes. The difference in the bending elasticity could be read out electrochem...

even though the use of enzymes as useful analytical reagents when immobilized onto a transducer such as an electrochemical device has been reported in the literature for nearly two decades, the direct, i.e. unmediated electrochemistry of enzymes is, nevertheless, a rather recent development. efforts will be made to introduce the fundamental basis for protein-surface interactions with emphasis o...

BICUVOX.10 (Bi Cu V O ) might be a very attractive material for use in oxygen sensors, fuel cells and oxygen 2 0.1 0.9 5.35 separators. The electrochemical stability of BICUVOX.10 is an important factor for its future application. The electrochemical reduction and oxidation can be recognized very easily by the voltammetric technique. Our previous voltammetric measurements were made on 3-electro...

Elimination voltammetry with linear scan (EVLS) represents the fast and simple improvement of linear-sweep or cyclic voltammetric results. Through the various elimination functions, EVLS offers a new tool not also for better understanding of complex electrochemical processes on the surface of working electrodes, but also for improving the sensitivity of electrochemical measurements. The paper i...

Aptasensors based on stripping voltammetry exhibit several advantages, such as high sensitivity and multi-target detection from stripping voltammetric technology, and high selectivity from the specific binding of apamers with targets. This review comprehensively discusses the recent accomplishments in signal amplification strategies based on nanomaterials, such as metal nanoparticles, semicondu...
