Professor Jerzy Radecki – Head


Jerzy Radecki obtained his M.Sc. degree at the Department of Organic Chemistry of Nicholas Copernicus University in Toruń in 1973. In 1980, he received a Ph.D. degree at the same University. Since 1980 till 1998, he was worked at the Olsztyn University of Agriculture and Technology. In 1993, he received a D.Sc. degree at this University. In 1985 he visited St. John’s College of Oxford University. He spent  one year (from June 1989 to May 1990) as post-doctoral fellow at the Department of Analytical Chemistry of University of Sao Paulo. In 1990, he was granted with a fellowship in the National Institute for Environmental Studies in Tsukuba, Japan.

Since 1998, he is working as a head of Department of Biosensors in the Institute of Animal Reproduction and Food Research of Polish Academy of Sciences in Olsztyn.

Jerzy Radecki is the editor-in-chief of the “Polish Journal of Environmental Studies” (http://www.pjoes.com) from 1992.

He is the co-ordinator of Safety Food Network ( http://www.pan.olsztyn.pl/interfood/), founder and the local co-ordinator  of Polish Supramolecular Chemistry Network (http://www.gscn.org). He was a coordinator of EU Marie Curie Host Fellowships grants  for Transfer of Knowledge (ToK): “Cenexfood” and “Food-Biosens”   (http://biosensors.pan.olsztyn.pl).

Currently, he is Polish representative of COST Action CM1005 “Supramolecular Chemistry in Water”.

Generally, his research interest concerns the developing of the new sensors and biosensors based on the intermolecular recognition processes occurring at the border of the aqueous and organic phase. Particularly, he is interested in functionalization of  surface of solid electrodes, gold as well as carbon, with “host” molecules, which are responsible for  selective and sensitive “guest” molecules (analytes) recognitions. The modified surfaces are characterized  by  electrochemical techniques  and  microscope: atomic force and scanning tunnelling. He is working on not only analytical aspects of developed sensors, but  on the elaboration of the mechanism of analytical signal generation as well.

The sensors he is working on could be divided into two main groups. One is based on ion-channel mimetic mode, in which the intermolecular recognitions phenomena are traced by changes of  the accessibility redox marker present in the aqueous solutions, towards the electrode surfaces. The another type of sensors are based on redox active monolayer deposited on the surface of solid electrodes. The redox centres play double role: as the  recognition units as well as transductor.  For sensors fabrications he has applied the synthetic receptors such as: corroles, calix[4]pyrroles,  calixarenes, dipyrrometenes, oligocarbazoles macrocyclic polyamines.  In biosensors, naturally occurring  “host” molecules – mainly proteins and single strands of DNA  are accommodated.

The developed sensors and biosensors are worked on the amperometric, voltammetric,  impedimetric as well as potentiomteric mode.
