abstract
Recent applications of flow-based analytical methods for pesticide determinations are reviewed. This
review is focused on the description of electrochemical and optical flow sensors, describing the most
relevant applications in this field. The different approaches employed up to date in electrochemical
biosensors, together with the possible modifications in the flow methodology and the development
of multiparameter flow-through optosensors have also been extensively described. Advantages, hand-
icaps and current trends of each detection technique are critically discussed. The article ends up with
a comparison between flow-based analytical methods and chromatography when applied to pesticide
determination.

Eulogio J. Llorent-Martínez, Technical Researcher,
was born in Jaén, Spain, in 1981. He received the
chemistry degree and the Ph.D. degree (summa cum
laude) from the University of Jaén in 2003 and 2008,
respectively. He is currently developing his research
in the Department of Physical and Analytical Chem-
istry in the University of Jaén. He is mainly interested
in the development of new automatic optosensors
applied to clinical, food and environmental analysis,
as well as researching in atomic spectrometry (ICP-
MS) and gas chromatography–mass spectrometry.
Pilar Ortega Barrales, Lecturer in Analytical Chem-
istry, her studies in Chemistry were in both the
University of Jaén and Granada. She is lecturer in
the University of Jaén since 1994 and she got her
Ph.D. degree there in 1996 under the topic of solid
phase spectroscopy. In 2000 and 2002 she spent two
researches in Corrientes in Argentine and in Vienna in
Austria, respectively. She has supervised three Ph.D.
Thesis about flow through optosensors. Actually her
research topics are flow through sensors as well as
applications of ICP-MS.
María Luisa Fernández de Córdova Lecturer in Ana-
lytical Chemistry at the University of Jaén (Spain)
from 2000. She received in 1994 her Ph.D. in chem-
ical sciences from the University of Jaén. Her main
research interests are analysis of olive oil and lumi-
nescent flow-through optosensors for agrochemical,
clinical and environmental analysis. At present, she is
participating in a research project related to analysis
of cultural heritage, concretely of mocarabes plaster
works in the Palace of Alhambra (Granada-Spain).
Antonio Ruiz Medina, Lecturer in Analytical Chem-
istry, was born in Jaén, Spain, in 1971. He finished
his studies in chemistry at the University of Granada
(1994). In 1996 he was awarded a Ph.D. in the Depart-
ment of Physical and Analytical Chemistry at the
University of Jaén. He served as postdoctoral posi-
tions at both the University of Florida (USA) and
Vienna University of Technology (Austria). In 2001 he
became assistant professor of analytical chemistry at
the University of Jaén and two years later a lecturer.
His research interest lies in the development of new
automatic optosensors and also performing research
in atomic spectrometry and gas chromatography
techniques.
