Research activity

  • molecular probes
  • fluorescence
  • bioluminescence
  • microscopy
  • chemical biology
  • biological chemistry
  • live-cell imaging
  • cell lines
  • assays
  • HTS
  • high throughput screening
  • free radicals
  • metal ions
  • proteins/enzymes
  • biomarkers
  • prodrugs
  • FRET
  • FLIM
  • MINFLUX
  • COVID-19
     

The main aim is to develop low-molecular weight chemical tools to image, study and control biological systems through mapping and subsequently modifying interactions between biochemical targets in live cells (figure). In particular:

  • Fluorescent and bioluminescent molecular probes for sensing pairs of analytes to associate biochemical changes inside cells with the development of disease (e.g. lung and prostate cancer).

  • Non-genetic methods for in situ tagging of endogenous proteins to visualise endogenous proteins and study their interactions in live cells.

  • Multiplexing assays (based on small molecules) for high-throughput screening to improve the identification of most promising small molecule drug candidates and deciphering their mechanism of action (also within the ERIC EU-Openscreen  consortium and POL-Openscreen initiative)

  • molecular tools for super-resolution new generation fluorescent nanoscopy (resolution approx.. 1 nm) in live biological models

  • development of molecular tools and assays to study mechanisms of infection and searching for therapy against COVID-19

These tasks encompass, among others:

  • Organic synthesis of probes (low molecular weight fluorophores and bioluminophores) 

  • Comprehensive spectroscopic analysis (in cuvettes and on microplates) 

  • Assay development and fluorescent imaging of live cells with confocal microscopy (e.g. FRET and FLIM) and super-resolution nanoscopy (e.g. STED and MINFLUX)
