Title and abstract of prof. Andriy Mokhir’s lecture:
Singlet oxygen – responsive bioconjugates for control of biochemical processes and detection of nucleic acids in vitro and in live cells
Singlet oxygen (1O2) is a reactive molecule, which can be photogenerated from triplet oxygen in the presence of photosensitizers. In water lifetime of 1O2 is only 3.5 µs, which limits its sphere of action to several hundred nanometers. Therefore, the effect of this reagent is well localized after its generation that allows for many interesting biological applications. In particular, the group of Mokhir develops substrates/bioconjugates, which can release active biomolecules or fluorophores upon their reaction with 1O2. These substrates/bioconjugates are applied to control biochemical processes (e.g. RNA interference, RNAi) and to detect biomolecules (e.g. rRNA and mRNAs) in live cells [1-4]. These topics will be discussed during the presentation of A. Mokhir.
