ESEAC 2020 is a continuation of the successful series of biannual international meetings introduced by Professor Malcolm R. Smyth in 1986 in Dublin City University. The conference has a broad scope covering all fields of modern electroanalysis – from theoretical aspects to practical applications. This Conference brings together the most outstanding research in electroanalytical chemistry from across Europe and the world. Contributions of young researchers are strongly encouraged. We count on a successful meeting, which provides an exciting forum for the presentation of recent research, informal discussions, exchange of ideas and new co-operations in the field of electroanalysis.
