Electrochemistry often represents an invaluable tool in sensing; as an example, this holds for opaque media, where optical techniques are impractical. In many situations electrochemical sensors alone are suitable to solve the problems, in other cases they complement optics, or other analytical techniques, in giving a complete picture of the system under exam.
The recent realisation and widespread diffusion of novel conducting materials regard i) intrinsically conducting polymers; ii) redox polymers; iii) metallopolymers; iv) carbon nanotubes; v) graphene; vi) metal nanoparticles; vii) metal oxide nanoparticles; etc. A large number of novel materials is potentially well suitable for application in electroanalysis. However, only a minor fraction of them has been tested as electrode materials for sensing, in ‘synthetic’ solutions and, even less, in real matrices. Moreover, a variety of nanocomposites, differently combining two or even more of the components listed above, has also opened new, extremely wide room to electroanalyisis.
In order not to adopt the expensive and time consuming try-and-error approach, full characterisation of the systems realised is necessary, in order to exploit it as a feedback to best material and device performances. With this respect, aiming at defining applicative procedures, the attitude deriving from expertise in analytical sciences is required. Furthermore, the realisation of a complete sensing device, even including features for full automation of the measurement process, requires engineering expertise. Last but not least, in the too often followed ‘empirical’ approach, the lack of a strong enough electrochemical culture is evident, which constitute a heavy drawback when aiming at realising an electrochemical device…
The interdisciplinary science of electrochemical sensing is not only open to disciplines very different from one another but, even more important, forces to melt all the necessary expertises in a common work to a common goal.
The lack of adjectives in front of the Sensors title of the journal and the ensemble of authors collected so far, aim at constituting a strong encouragement to proceed along this direction. The limit to the contributions to this Special Issue is only fixed by the ‘electrochemical’ transduction of the sensing system.
