We invite applications for a Ph.D. position in the research group Fluorescent Probes under the supervision of Dr. Peter Šebej https://www.recetox.muni.cz/vyzkum/lide/dr-peter-sebej



Polymethine dyes and their conjugates for labelling in biomedical applications

Modern diagnostic methods are often based on molecular biology and immunochemistry approaches allowing to tag and visualize tissues, cells, and cellular structures based on various types of electromagnetic radiation. Conjugates of fluorescent molecules and nanoparticles are among the most often used visualization modalities. We aim to combine molecular design, organic synthesis, bioconjugation and cell labelling with tags emitting primarily in tissue transparent window to overcome limitations of traditional fluorescent tags.

The candidate will perform synthesis and characterization of organic small molecular fluorophores alone and in larger covalent constructs and will study their properties. Assessment of structure-properties relationship will allow to rationally design such dyes and apply them in vitro and in vivo in models of various complexity. Highly motivated and skilful candidates will have the opportunity to considerably extend their graduate training in chemistry by learning advanced spectroscopic methods, photochemistry, bioconjugations, and will also take part in close collaboration with biologists.
