Preface

Since biological sensors were first reported several decades

ago, electrochemistry, being one of the few known transduction

methods for biological processes and biosensors, has played a

pivotal role in the development of these devices. Electrochemical

transduction, a generic concept involving techniques such as

amperometry, conductimetry, potentiometry, square-wave voltam-

metry impedance, and electrochemiluminescence, is currently one

of the main strategies used in the biosensor field. The latter

includes enzyme electrodes, immunosensors, protein sensors, DNA

sensors, and biochips. The explosion of activity in nanoscience and

nanotechnology and their huge success have profoundl ...
