Dr. Andrea Dandić's research focuses on the design, synthesis, and structural characterization of fluorescent probes for the detection of small biomolecules, primarily H₂S. In addition, she investigates the design, synthesis, structural characterization, and modification of heterocyclic compounds with potential biological activity, with particular emphasis on structure–activity relationship (SAR) studies. Her research also includes the design and synthesis of sensors for analytical applications, including ion-pair-based sensors, covalently functionalized multi-walled carbon nanotube (MWCNT) sensors, and molecularly imprinted polymer sensors for potentiometric analysis. Her work emphasizes the optimization of sensor performance to achieve high sensitivity and selectivity toward analytes such as surfactants and pesticides. Her research also
