This volume is ba. sed on the presentations gi ven at the
ElectroFinnAnalysis conference held on J une 6-9, 1988 in
Turku-Abo, Finland. This event was the second in a series of
electroanalytical conferences. The first was held in Ireland 1986
and the next will be held in Spain 1990. The aim of these
conferences is tobring tagether scientists who use
electroanalytical methods in their research. This is also reflected
in the disposition of this volume where instrumentation and
applications from the different fields have their own chapters. The
editors are grateful to Mr. Johan Nyman, Mr. Kent Westerbolm and
Mr. Markku Lehto for their technical assistance during the
editorial work of this volume. Ari Ivaska Andrzej Lewenstam Ralf

This book discusses the ion fluxes and electron transfer processes
in biological membranes and artificial bio-films. It provides an
in-depth description of the processes at the interface between the
membrane/film and substrate electrode. Chapters include: ion
transfer and ion channels in biological membranes in health and
pathology; artificial membranes and films in electrochemical
modelling of ionic fluxes in membrane potential formation;
trasmembrane ion fluxes for lowering detection limits of
ion-selective electrodes; voltage detection in ion channels and
genetically-coded sensors; gating kinetics of voltage-dependent ion
channels; connecting up to the surface: exploiting molecular wires
for biosensing; electron transfer in and between redox
proteins/enzymes, protein voltammetry--direct electron transfer
between redox enzymes and electrodes; biological charge transfer
reactions in mitochondria and illnesses related to mutations in the
mitochondrion; electron transfer pathways between living bacterial
cells and electrodes; biocomputing systems based on electrically
wired enzymes; electron transfer pathways in photosystems, and
reaction mechanism of multicopper blue oxidases related to their
use in biodevices such as biofuel cells.
