In 1991 Professor Itamar Willner (Department of Organic Chemistry, Hebrew University) invited me to conduct research in his group. During my short stay in his group I studied modification of gold electrodes with monolayers and polymers and monolayer and multilayer immobilization of redox proteins electrically contacted with electrodes via tethered electron relay groups. I brought into this study some methods and approaches previously developed in Russia that nicely fitted needs of the group. The main results of this period include:

  monolayer and multilayer immobilization of nitrate reductase and glutathione reductase electrically contacted with electrodes via tethered viologen groups (#43 and #58 in the publication list),

  multilayer immobilization of glucose oxidase electrically contacted with electrodes via tethered ferrocene groups (#50 in the publication list),

  demonstration of Marcus-type distance-dependent electron transfer reactions on monolayer modified electrodes (#44 in the publication list).
